Below are the latest papers in condensed matter and materials science, organized by their most recent publication dates.
This study demonstrates that prototypical altermagnets CrSb and MnTe host locally chiral phonon modes that, when symmetry is lowered to lift momentum-space cancellation, couple to their unique spin-split electronic bands via momentum-dependent interactions, establishing these materials as a promising platform for chiral phononics and spin-selective lattice control.
This paper analyzes the high-temperature operation of III-nitride HEMTs by examining the impact on material and device properties, evaluating strategies to mitigate thermal effects, and assessing their stability across various applications while highlighting remaining design challenges.
This study investigates the magnetotransport properties and electronic band structure of the antiferromagnetic compound EuNiAs, revealing complex metamagnetic transitions, hole-dominated multi-band conductivity, and significant magnetic-field-induced changes in the electronic structure that are well-supported by both experimental data and ab-initio calculations.
This paper demonstrates that ultrafast double pump-probe spectroscopy can directly observe and control the anharmonicity of single Raman phonon modes in thermoelectric materials like SnTe and SnSe by measuring frequency shifts as a function of oscillation amplitude, thereby disentangling coherent contributions from quasi-harmonic effects and offering new pathways for material engineering and understanding optically induced phase transitions.
This paper proposes a general strategy for the electrical control of topological magnons in bilayer ferromagnetic insulators, where a vertical electric field modulates interlayer potential and Heisenberg exchanges to tune band topology and nonreciprocal dynamics through competition with intrinsic Dzyaloshinskii-Moriya interactions.
This study reports the discovery of robust nonreciprocal magnons in layered honeycomb antiferromagnets VPX3 (X=S, Se, Te), revealing their dependence on layer number, interlayer coupling, and magnon interactions, while demonstrating an asymmetric periodic response to the Néel vector that offers a novel method for probing 2D antiferromagnetic order.
Using scanning tunneling microscopy with superconductive tips, this study identifies subsurface magnetic scatterers in bulk FeSe that generate particle-hole symmetric gap modulations and Josephson current oscillations consistent with pair-breaking scattering interference, establishing PBSI as a viable mechanism for gap modulations in superconductors without preexisting density wave orders.
This paper demonstrates that the proposed energetic coupling between Field Dislocation Mechanics and the Phase Field Crystal model is fundamentally limited because it fails to capture dislocation topology, transmits boundary conditions diffusively rather than elastically, and cannot prevent unnatural core spreading, thereby rendering it ineffective for integrating dislocation mechanics with crystallography.
This paper utilizes a non-Markovian quantum master equation to demonstrate that the elusive inertial magnetization dynamics observed in ultrafast experiments originate from coherent magnon-phonon coupling with optical lattice vibrations, thereby explaining picosecond nutation and offering new avenues for terahertz spin control.
The paper introduces "vitriflow," a computational framework that transforms the implicit parameters of melt-quench molecular dynamics into an explicit, material-specific decision chain to generate reproducible, calibrated ensembles of amorphous structures for diverse materials like silica, silicon nitride, and samarium oxide.
