      Spacetime or ‘event’ cloaking was recently introduced as a concept, and the theoretical design for such a cloak was presented for illumination by electromagnetic waves.

      P. Kinsler and M. W. McCall describe how event cloaks can be designed for simple wave systems, using either an approximate ‘speed cloak’ method, or an exact full-wave one (pp. 51–62).

      Electron quantum optics in ballistic chiral conductors (pages 1–30)

      Erwann Bocquillon, Vincent Freulon, François D. Parmentier, Jean-Marc Berroir, Bernard Plaçais, Claire Wahl, Jérome Rech, Thibaut Jonckheere, Thierry Martin, Charles Grenier, Dario Ferraro, Pascal Degiovanni and Gwendal Fève

      Article first published online: 4 DEC 2013 | DOI: 10.1002/andp.201300181

      The edge channels of the quantum Hall effect provide one dimensional chiral and ballistic wires along which electrons can be guided in optics like setup. Electronic propagation can then be analyzed using concepts and tools derived from optics. After a brief review of electron optics experiments performed using stationary current sources which continuously emit electrons in the conductor, this paper focuses on triggered sources, which can generate on-demand a single particle state. It first outlines the electron optics formalism and its analogies and differences with photon optics and then turns to the presentation of single electron emitters and their characterization through the measurements of the average electrical current and its correlations. This is followed by a discussion of electron quantum optics experiments in the Hanbury-Brown and Twiss geometry where two-particle interferences occur. Finally, Coulomb interactions effects and their influence on single electron states are considered.

      Crossing disciplines - A view on two-dimensional optical spectroscopy (pages 31–49)

      Agata M. Brańczyk, Daniel B. Turner and Gregory D. Scholes

      Article first published online: 29 NOV 2013 | DOI: 10.1002/andp.201300153

      Recent interest in the role of quantum mechanics in the primary events of photosynthetic energy transfer has led to a convergence of nonlinear optical spectroscopy, condensed matter and quantum physics on the topic of energy-transfer dynamics in pigment-protein complexes. The convergence of these communities has unveiled a mismatch between the background and terminology of the respective fields. To make connections, we provide a pedagogical guide to understanding the basics of two-dimensional spectra aimed at researchers with a background in quantum mechanics and condensed matter.

      Cloaks, editors, and bubbles: applications of spacetime transformation theory (pages 51–62)

      Paul Kinsler and Martin W. McCall

      Article first published online: 19 NOV 2013 | DOI: 10.1002/andp.201300164

      Spacetime or ‘event’ cloaking was recently introduced as a concept, and the theoretical design for such a cloak was presented for illumination by electromagnetic waves [McCall et al., J. Opt. 2011]. Here it is described how event cloaks can be designed for simple wave systems, using either an approximate ‘speed cloak’ method, or an exact full-wave one. Further, details of many of the implications of spacetime transformation devices are discussed, including their (usually) directional nature, spacetime distortions (as opposed to cloaks), and how leaky cloaks manifest themselves. More exotic concepts are also addressed, in particular concepts that follow naturally on from considerations of simple spacetime transformation devices, such as spacetime modeling and causality editors. A proposal for implementing an interrupt-without-interrupt concept is described. Finally, the design for a time-dependent ‘bubbleverse’ is presented, based on temporally modulated Maxwell's Fisheye transformation device (T-device) in a flat background spacetime.

      Superconductivity, diamagnetism, and the mean inner potential of solids (pages 63–78)

      J. E. Hirsch

      Article first published online: 18 OCT 2013 | DOI: 10.1002/andp.201300147

      The mean inner potential of a solid is known to be proportional to its diamagnetic susceptibility. Superconductors exhibit giant diamagnetism. What does this say about the connection between superconductivity and mean inner potential? Nothing, according to the conventional theory of superconductivity. Instead, it is proposed that a deep connection exists between the mean inner potential, diamagnetism, and superconductivity: that they are all intimately linked to the fundamental charge asymmetry of matter. It is discussed how this physics can be probed experimentally and what the implications of different experimental findings would be for the understanding of superconductivity.

      Nodal theorems for the Dirac equation in d ≥ 1 dimensions (pages 79–86)

      Richard L. Hall and Petr Zorin

      Article first published online: 1 OCT 2013 | DOI: 10.1002/andp.201300161

      A single particle obeys the Dirac equation in inline image spatial dimensions and is bound by an attractive central monotone potential that vanishes at infinity. In one dimension, the potential is even, and monotone for inline image The asymptotic behavior of the wave functions near the origin and at infinity are discussed. Nodal theorems are proven for the cases inline image and inline image, which specify the relationship between the numbers of nodes n1 and n2 in the upper and lower components of the Dirac spinor. For inline image, inline image whereas for inline image inline image if inline image and inline image if inline image where inline image and inline image This work generalizes the classic results of Rose and Newton in 1951 for the case inline image Specific examples are presented with graphs, including Dirac spinor orbits inline image

      On non-equilibrium photon distributions in the Casimir effect (pages 87–101)

      Vanik E. Mkrtchian and Carsten Henkel

      Article first published online: 25 OCT 2013 | DOI: 10.1002/andp.201300135

      The electromagnetic field in a typical geometry of the Casimir effect is described in the Schwinger–Keldysh formalism. The main result is the photon distribution function (Keldysh Green function) in any stationary state of the field. A two-plate geometry with a sliding interface in local equilibrium is studied in detail, and full agreement with the results of Rytov fluctuation electrodynamics is found.

      Master equation approach to conductivity of bosonic and fermionic carriers in one- and two-dimensional lattices (pages 102–111)

      Andrey R. Kolovsky

      Article first published online: 4 NOV 2013 | DOI: 10.1002/andp.201300169

      The master equation approach to diffusive current of bosonic or fermionic carriers in one- and two-dimensional lattices is discussed. This approach is shown to reproduce all known results of the linear response theory, including the integer quantum Hall effect for fermionic carriers. The main advantage of the approach is that it allows to calculate the current beyond the linear response regime where new effects are found. In particular, the Hall current can be inverted by changing orientation of the static force (electric field) relative to the primary axes of the lattice.

      Broadband efficient light absorbing in the visible regime by a metananoring array (pages 112–117)

      Shuiyan Cao, Weixing Yu, Lingtong Zhang, Cheng Wang, Xuming Zhang and Yongqi Fu

      Article first published online: 19 NOV 2013 | DOI: 10.1002/andp.201300198

      The broadband efficient light-absorbing property of a metamaterial-based subwavelength nanoring array in visible regime is reported. The nanoring array can absorb light efficiently with an average absorptivity of 0.97 over the whole visible waveband. In addition, it is found that this kind of super light-absorbing capability is independent of the incoming light polarization state and can maintain an average of 0.9 for an incident angle as large as ±60° under TM illumination. The perfect absorbing property of the metamaterial-based nanoring array is attributed to the synergetic effect of the Fabry–Perot resonance and the localized surface plasmon resonance enhancement.
