      What next in fundamental physics in space

      R. Battiston

      Article first published online: 24 NOV 2015 | DOI: 10.1002/andp.201500250

      Modern fundamental science is unbelievably young. During the last few centuries physics has made gigantic steps, sometimes revolutions, still today we address in a convincing manner only a pitiful 5% of the universe around us. The theoretical framework which let us understand the 5% tells us that there is a 95% of new forms of energy and matter to be discovered and understood. It is likely that in order to find the answer to these fundamental issues we should turn our attention to the same field which has spurred them: the Universe and the flood of radiation which is reaching us from its depths.

      Particle accelerators have been extraordinary discovery tools since the beginning of particle physics exploration. But accelerator's sizes and costs have now reached a critical limit, while the particle physics experiments require always higher energies. Is it time for a revolution in accelerator techniques or we can still rely in conventional methods? The next generation of discovery machines is presented together with the research on going in novel acceleration techniques.

    1. Extra dimensions and phase experiments

      Paul S. Wesson

      Article first published online: 19 NOV 2015 | DOI: 10.1002/andp.201500277

      Thumbnail image of graphical abstract

      In modern Kaluza-Klein theories which successfully unify gravity, electromagnetism and a scalar field, null geodesics in five dimensions lead to simplified expressions for phase shifts in four-dimensional spacetime. It might be possible to test for an extra dimension by experiments such as those where neutron interferometry is used to measure the Aharonov-Bohm effect.

    2. Strong light-matter coupling between a molecular vibrational mode in a PMMA film and a low-loss mid-IR microcavity

      Merav Muallem, Alex Palatnik, Gilbert D. Nessim and Yaakov R. Tischler

      Article first published online: 17 NOV 2015 | DOI: 10.1002/andp.201500282

      Thumbnail image of graphical abstract

      We present a microcavity phonon-polariton system that is derived from coupling cavity-confined mid-IR photons to the vibronic transition of an organic material. In particular, to achieve strong phonon-photon coupling, we coupled the carbonyl stretch vibrational transition of a polymethyl methacrylate film to the photonic resonance of a low optical-loss microcavity, which consisted of two Ge/ZnS dielectric Bragg reflectors. Transmission measurements show two distinct transmission peaks that are energetically shifted from the bare phonon and cavity resonances, indicating Rabi-splitting and the realization of polaritonic states.

    3. Statistical mechanics of holonomic systems as a Brownian motion on smooth manifolds

      Fabio Manca, Pierre-Michel Déjardin and Stefano Giordano

      Article first published online: 6 NOV 2015 | DOI: 10.1002/andp.201500221

      Thumbnail image of graphical abstract

      The formulation of statistical mechanics based on Langevin and Fokker-Planck equations is typically developed for particles without mechanical constraints. However, the constrained statistical mechanics is indispensable to study several statistical properties of molecular assemblies of interest in chemistry, physics and biology. Therefore, in this paper we analyze arbitrary holonomic scleronomous systems by specializing the Lagrange and Hamilton equations of motion to those of the Langevin dynamics on a smooth manifold.

    4. Electrochemical structure-switching sensing using nanoplasmonic devices

      Sergiy Patskovsky, Anne-Marie Dallaire, Andre-Pierre Blanchard-Dionne, Alexis Vallée-Bélisle and Michel Meunier

      Article first published online: 30 OCT 2015 | DOI: 10.1002/andp.201500229

      Thumbnail image of graphical abstract

      Plasmonic-based electrochemical biosensing (eSPR) combines the advantages of highly selective structure-switching biosensing with the flexibility and sensitivity of nanoplasmonic structures. The resulting devices are promising for reliable biosensing in complex and contaminated liquid samples and are compatible with wide-field microscopy. They show a potential for realizing a standalone portable device with multiplexed and disposable sensing chips for investigation of untreated blood samples.

    5. Quantum exclusion of positive cosmological constant?

      Gia Dvali and Cesar Gomez

      Article first published online: 29 OCT 2015 | DOI: 10.1002/andp.201500216

      Thumbnail image of graphical abstract

      “Cosmological constant was originally introduced by Einstein. In classical general relativity this source creates a metric of constant space-time curvature, the so-called de Sitter space. In the context of modern quantum field theory this possibility causes a tremendous puzzle, that goes under the name of the Cosmological Constant Problem: Why is the observational bound on the cosmological term by 120 orders of magnitude smaller then its naturally-expected value set by the Planck scale? In the present paper, a very different road is suggested, by fundamentally changing the nature of the question. Instead of a naturalness problem the cosmological constant has to be viewed as a question of quantum consistency; can quantum gravity tolerate a truly constant classical source? In the present paper we provide evidence that de Sitter space cannot be eternal in quantum theory.”

    6. Future e+e− linear colliders - physics motivation and physics reach

      Hitoshi Yamamoto

      Article first published online: 29 OCT 2015 | DOI: 10.1002/andp.201500231

      Thumbnail image of graphical abstract

      The discovery of the Brout-Englert-Higgs boson by the LHC opened a new era of particle physics, and the scientific case for the International Linear Collider (ILC) has become ever more compelling. The measurement accuracies of the Higgs couplings are such that one ILC is typically equivalent to 100 ultimate upgraded LHC's running simultaneously. Furthermore, if a new particle is within the energy reach of the ILC, the ILC would be able to find it even when the LHC has difficulty detecting it. We briefly over view the physics capability of the ILC.

    7. Solvable potentials with exceptional orthogonal polynomials

      Ashley Arsenault, Sheldon Opps and Nasser Saad

      Article first published online: 26 OCT 2015 | DOI: 10.1002/andp.201500255

      Two different but partner potentials are sharing exactly the same energy spectrum. The supersymmetric eigenfunctions derived from one another by simple creation and annihilation operators and they generate classes of exceptional orthogonal polynomials. A recent topic of a great mathematical interest.

      Electromagnetic neutrinos in laboratory experiments and astrophysics

      Carlo Giunti, Konstantin A. Kouzakov, Yu-Feng Li, Alexey V. Lokhov, Alexander I. Studenikin and Shun Zhou

      Article first published online: 26 OCT 2015 | DOI: 10.1002/andp.201500211

      Thumbnail image of graphical abstract

      The discovery of the Higgs boson at LHC was another milestone achievement for the Standard Model. However, neutrinos do not fit into this extremely successful theory of particle physics. Various theoretical scenarios beyond the Standard Model predict electromagnetic interactions of neutrinos. We focus on electromagnetic neutrinos as potential messengers of new physics in laboratory experiments and astrophysical processes.

      An introduction is given to the physics with the Large Hadron electron Collider (LHeC), a new generation inline image and inline image collider exploring the accelerator energy frontier with a prospect to the FCC-he. The LHeC is designed to become the finest new microscope for substructure of matter worldwide exploring new physics, and the next accelerator to study the Higgs boson, which will enable the LHC to be transformed into a precision physics facility of increased value.

    1. Non-interacting single-impurity Anderson model: solution without using the equation-of-motion method

      Zakaria M.M. Mahmoud and Florian Gebhard

      Article first published online: 16 OCT 2015 | DOI: 10.1002/andp.201500259

      Thumbnail image of graphical abstract

      Single-particle problems can be solved exactly, in principle. For beginners in many-particle physics, however, it is helpful to know how this is done in practice. The present work shows how to derive explicitly ground-state and spectral properties for the non-interacting symmetric single-impurity Anderson model (SIAM). The formulae are also useful for researchers employing variational approaches to the interacting SIAM.

      Kichul Park, Junsu Lee, Young Tack Lee, Won-Kook Choi, Ju Han Lee and Yong-Won Song

      Article first published online: 15 OCT 2015 | DOI: 10.1002/andp.201500245

      Thumbnail image of graphical abstract

      A black phosphorus (BP) D-shaped fiber saturable absorber is constructed to employ evanescent field interaction to use the nonlinear optical absorption of BP for passive mode-locking operation in C-band. The constructed device exhibited light modulation depth of ∼3.31% with saturation peak power density of 12.5 MW/cm2, and generated mode-locked pulses with duration of ∼2.18 ps with repetition rate of 15.59 MHz.

    1. On the Trail of the Higgs Boson

      Michael E. Peskin

      Article first published online: 11 SEP 2015 | DOI: 10.1002/andp.201500225

      Thumbnail image of graphical abstract

      This article reviews the role of the Higgs field in the Standard Model of particle physics and discusses the question of why the gauge symmetry of the model is spontaneously broken. Solutions to this question require new particles and forces. General properties of these new particles, and some specific examples, are presented.

    2. Cosmological implications of Higgs field fluctuations during inflation

      A. V. Grobov, R. V. Konoplich and S. G. Rubin

      Article first published online: 8 SEP 2015 | DOI: 10.1002/andp.201500127

      Thumbnail image of graphical abstract

      The discovery of the Higgs boson and measurements of its mass play an important role in our understanding of the early universe. They indicate that the Higgs potential becomes unstable at large energy scale and this instability is cosmologically relevant. Large quantum fluctuations during inflation could result in a universe landed in wrong vacuum. In this paper it is shown that depending on the instability scale the fate of the universe could be drastically different.

    3. An analogue of the quantum Hall conductivity for a magnetic quadrupole moment

      Itallo Costa Fonseca and Knut Bakke

      Article first published online: 8 SEP 2015 | DOI: 10.1002/andp.201500183

      Thumbnail image of graphical abstract

      The quantum dynamics of a moving particle with a magnetic quadrupole moment that interacts with electric and magnetic fields is introduced. Then, it is discussed which conditions the external fields must satisfy so that an analogue of the Landau quantization can be obtained. Finally, by dealing with the lowest Landau level associated with the magnetic quadrupole system, an analogue of the quantum Hall conductivity is obtained.

    1. Charge-induced electromagnetic resonances in nanoparticles

      Miroslav Kocifaj, Jozef Klačka, František Kundracik and Gorden Videen

      Article first published online: 24 AUG 2015 | DOI: 10.1002/andp.201500202

      Thumbnail image of graphical abstract

      We report new developments in electromagnetic scattering theory in which charge-induced resonances in nanoparticles result from interaction with electromagnetic radiation. The net surface charge can be a significant factor in many systems, for instance, colloids of metallic particles. Among colloidal particles at liquid interfaces, charged nanoparticles are a fertile subject of new technological concepts and can be decisive in the development of new devices and novel technologies in the nanosciences, such as optical attenuators, modulators, and switches that can be turned on or off through the application of charge. For electrically charged particles, the resonant excitation of surface modes is governed by exc ess charges deposited on the particle surface. Charge-induced resonances appear in such systems that can reproduce previously unexplained phenomena, for instance, amplified microwave attenuation observed in sandstorms.

      Low-energy precision tests of the standard model: a snapshot

      David W. Hertzog

      Article first published online: 7 AUG 2015 | DOI: 10.1002/andp.201500167

      Thumbnail image of graphical abstract

      The deserved world's attention on the re-energized atom-smashing power of the Large Hadron Collider anticipates the discovery of new physics beyond the Standard Model. However, there is a quieter, alternative and complementary approach, which does not rely on Earth-shattering high energy collisions, but instead uses exquisite precision to hunt for deviations from Standard Model expectations. In this review, we describe a series of these unique experiments that may have far reaching implications.

      The continuous variable quadripartite entanglement generated by the coupled type I second harmonic generation are investigated below threshold. The entanglement degree versus normalized frequency, pump parameter, and coupling parameter are analyzed. The four output fields are proved to be entangled beams in separable locations. The result shows that the coupled system can be used to produce compact multimode entangled resource for quantum communication.

      Article first published online: 31 JUL 2015 | DOI: 10.1002/andp.201500114

      Thumbnail image of graphical abstract

      There is overwhelming evidence for dark matter in our Universe. So far, it is based on indirect observations, where its influence on visible matter is studied. A large programme of experiments aiming to directly detect this new form of matter in the laboratory, in space or to produce it at particles colliders is underway. These approaches are complementary to one another and exciting new results are expected within the current decade.

      Perhaps the most perplexing fact about our Universe is that it is accelerating today due to some unknown form of Dark Energy which makes up 65% of the total energy density pie. In this brief article we discuss possible links between the Higgs field and the nature of Dark Energy and ask how might we test for the latter now that we know something about the former.

      Matter-antimatter asymmetry - aspects at low energy

      Lorenz Willmann and Klaus Jungmann

      Article first published online: 1 JUL 2015 | DOI: 10.1002/andp.201500008

      Thumbnail image of graphical abstract

      The dominance of matter over antimatter in our universe today is an obvious and puzzling fact. It cannot be sufficiently explained in present physical frameworks built on symmetric conditions at the big bang. Known sources of CP violation are insufficient to explain the matter-antimatter asymmetry. CPT violation could alternatively provide an explanation and is therefore being searched for as well as are differences in the properties of particles and their antiparticles. New precision experiments at low energies provide for a promising way towards resolving this puzzle.

      The Standard Model of particle physics is extremely successful in describing the properties of matter and forces, although it leaves fundamental questions unanswered, like the existence of dark matter, the asymmetry of matter anti-matter in the universe, and the neutrino masses. Cosmic particles offer unique opportunities to address these many fundamental questions. Tests done with present and planned future missions are reviewed.

      Phenomenology of the Pyramid Scheme

      Tom Banks

      Article first published online: 22 JUN 2015 | DOI: 10.1002/andp.201500210

      Thumbnail image of graphical abstract

      This article gives a brief summary of the Pyramid Schemes, a class of supersymmetric models of particle physics below the 100 TeV scale, which is compatible both with existing experimental constraints and the very low scale of supersymmetry breaking implied by the idea of Cosmological Supersymmetry Breaking. This idea leads to novel solutions to some of the fine tuning problems of the conventional approach to particle phenomenology based in effective quantum field theory. Most notable is the novel resolution of the absence of CP violation in strong interaction physics. The Pyramid Schemes, in a certain range of parameters predict that squarks are much lighter than gluinos and that the lightest supersymmetric particle, apart from the gravitino, is a supersymmetric partner of one of the right handed leptons.

      The Higgs boson discovery at LHC starts an exciting program to understand the role of this particle in connection with New Physics and Cosmology. Supersymmetry is the best motivated and thoroughly formulated model of New Physics predicting a light Higgs and able to explain dark matter. This paper connects the study of the Higgs boson with the search for supersymmetry and dark matter at colliders and underground experiments.

      There are many good reasons to favor supersymmetry as an extension of the Standard Model. But it may be more hidden than often expected and one should pursue experimental search for it, keeping in mind several different scenarios.

      The discovery of non-zero neutrino mass and mixing has opened a portal to physics beyond the Standard Model. The next decade promises critical developments with a program of ambitious experiments that will probe the fundamental nature of neutrino mass and mixing, and provide important clues on the primordial matter-dominance of the universe. The image shows an electron-like Cherenkov ring in the Super-Kamiokande detector arising from the conversion of a muon neutrino produced in the T2K neutrino beam to an electron neutrino through the neutrino oscillation process (image: courtesy of the T2K collabortion and the Kamioka Observatory, ICRR, University of Tokyo).

      In the coming flavour precision era a multitude of new quark and lepton flavour observables will be measured with high precision and theoretical calculations will improve. This will hopefully bring the discovery of new physics beyond the Standard Model. Most importantly the unique role of quark and lepton flavour physics in the coming years will be to allow us with the help of quantum fluctuations to get insight into the dynamics at length scales as short as inline image). The requirements that have to be met for such a flavour expedition to the Zeptouniverse to be successful are summarized.

      Supersymmetry after the Higgs

      Article first published online: 21 APR 2015 | DOI: 10.1002/andp.201500005

      Thumbnail image of graphical abstract

      A brief review is given of the implications of a 126 GeV Higgs boson for the discovery of supersymmetry. The 126 GeV Higgs mass implies a large SUSY scale which explains the non-observation of sparticles thus far. The large scale also helps suppression of FCNC, CP violation effects and helps stabilize the proton against B&L violating dimension five operators. It is shown that the gluino, charginos, neutralinos, sleptons and a stop can be light and are the prime candidates for discovery at the LHC.
