We are excited to announce that our new journal Advanced Physics Research is now open for submissions!
Advanced Physics Research is an open-access journal that covers the whole gamut of physics from applied to fundamental studies with a strong emphasis on important and relevant topics. As a new flagship physics journal, Advanced Physics Research aims to bridge the gap between the materials science and physics communities, remaining faithful to the core values of the physics community, and covering topics beyond those currently published in the well-recognized Advanced Materials journal.
On the Cover
Understanding how electronic and structural perturbations influence the magnetic properties of van der Waals magnets is crucial for designing and implementing next-generation spintronic applications of 2D materials. In article number 2300036, Evan J. Telford, Daniel G. Chica, and co-authors demonstrate how hydrostatic pressure and ligand substitution applied to CrSBr modulate the magnetic properties via a complex interplay of structural and electronic effects.
Nanochannel arrays serve as tractable models for elucidating the electrical response of the much larger cantankerous nanoporous membranes used in water desalination and energy harvesting systems. In article number 2300044, John Sebastian and Yoav Green demonstrate that a nanochannel array can be represented by a simple electrical circuit of ‘unit-cell’ resistances connected in parallel. The parallel circuit results from the formation of internal planes of symmetry that ensure that unit cells do not exchange flux between themselves. The front cover image shows a colormap of surfaces of high (red) and low (blue) constant electric potentials, while the green lines depict the planes of symmetry.
If a laser pulse is focused in a thin liquid layer between two glass plates, the induced stresses may cause a nearby surface nano-crack to be circularly extended around the laser focus, as shown by Claus-Dieter Ohl, Pedro A. Quinto-Su, and co-workers in article number 2300030. After repeated shots, the circular damage closes and a piece of glass is expelled, leaving behind a damage pattern remniscient of that created by a projectile.
The interplay between charge-to-spin conversion and magnetism is a long-standing unsettled issue in spintronics. In article number 2300017, Zhe Yuan, Jian-Wang Cai, and co-workers expermentally demonstrate, for the first time, that the spin Hall angle of a ferromagnetic metal (Fe) can be gradually reversed by controlling its magnetization. This marks an important advance in ferromagnetic-metal-based spin-orbitronics.

-  3 December 2023
By illuminating a clean zinc oxide surface with a few-cycle near-infrared light pulse and a pair of attosecond extreme ultraviolet pulses, an attosecond interferometry experiment is performed for the first time using an electron microscope. The combined spatio-temporal resolution is a significant step towards imaging optical fields and electronic excitations in heterogeneous environments with attosecond-nanometer precision.
In Situ Scattering Studies of Superconducting Vacancy‐Ordered Monoclinic TiO Thin Films
-  22 November 2023
Disorder, stemming from randomly distributed Titanium and Oxygen vacancies influences the transport properties of superconducting TiO thin films. In situ synchrotron X-ray scattering and atomic layer-by-layer synthesis using molecular beam epitaxy are used to understand the emergence of the vacancy-ordered monoclinic TiO phase. The ordering is correlated with reduced electronic disorder and a superconductor-to-metal transition providing insights and potential advancements in superconducting materials.

Terahertz Spectral Signatures of Ultrafast Spin Transports in Ferromagnetic Heusler Alloy
-  9 January 2023
The signature of ultrashort laser driven spin-dependent transport in the Co2FeSi interfaced with a Pt layer is imprinted on the terahertz emission. THz spin currents in Co2FeSi/Pt can be engineered by chemical ordering, interface roughness, and magnetization. Finally, the contributions are distinguished to the ultrafast spin currents from thermalization and optical excitation of majority spins in Heusler alloy.

Comprehensive discussions on the gating effects of ferroelectric copolymer and related applications are still scarce. This review provides a systematical summary of ferroelectric copolymer P(VDF-TrFE). We also discuss emerging opportunities in terms of optoelectronic devices, nonvolatile memories, neuromorphic devices, andnegative capacitance transistors. Additionally, existing problems and promising prospects for 2D semiconductor/P(VDF-TrFE) devices are further proposed.

The difference between P and PS, and how PS enters into the governing equations of triboelectric nanogenerator is considered. A 3D mathematical-physical model for the sliding mode freestanding TENGs is established to confirm the relationship between free charge distribution and dynamics of output power.

-  1 February 2023
A new method to compute the Taylor expansion of band dispersion is presented. It is implemented numerically, and can handle large and detailed models, particularly when the models are tuned through a higher order Van Hove singularity. This will aid the search for Fermi surface topological transitions and higher order Van Hove singularities in the band structure of real materials.
