This paper reports the observation and theoretical explanation of terahertz-induced magneto-photogalvanic effects in bulk CdHgTe crystals hosting Kane fermions, where resonant and nonresonant currents arise from cyclotron resonance, photoionization, and interband transitions driven by spin-dependent scattering mechanisms.
This paper reports the comprehensive study and theoretical modeling of the intensity-dependent saturation (bleaching) of the terahertz magneto-photogalvanic effect in CdHgTe crystals with Kane fermions, demonstrating how distinct absorption mechanisms can be independently analyzed to determine energy relaxation times across a wide range of radiation intensities.
This paper theoretically demonstrates that mode-selective parametric excitation and a proposed nonlinear cooling mechanism can dynamically control random telegraph noise in magnetic tunnel junctions, offering a pathway to accelerate switching speeds for probabilistic computing applications.
This paper establishes a topological classification of non-orientable Weyl semimetals using twisted (co)homology groups and exact sequences, thereby providing a coordinate-independent explanation for charge cancellation and predicting novel phenomena across non-Hermitian and inversion-symmetric systems.
This paper theoretically demonstrates a gate-tunable superconducting spin valve in a van der Waals ferromagnet/superconductor/ferromagnet trilayer, where electrostatic gating modulates the exchange field to continuously switch between standard, inverse, and triplet spin-valve regimes while inducing exotic non-BCS phenomena such as reentrant superconductivity and first-order phase transitions.
This tutorial article bridges the gap between the mathematical theory of geometric phases and experimental nanophotonics by explaining how the interaction of structured light with nanostructures creates geometric phases with underlying geometries distinct from those in conventional optics.
This paper predicts that magnetic topological materials, particularly magnetic Weyl semimetals like CoSnS, can achieve strong, broadband, and magnetic-field-free nonreciprocal thermal radiation in the infrared regime, establishing a predictive framework and quantitative design rules for next-generation thermal devices.
This paper demonstrates that in symmetry-broken rhombohedral graphene, valley domain walls act as impenetrable barriers in the metallic regime and require intervalley mixing to support supercurrents in the superconducting phase, highlighting the critical role of intervalley hybridization in governing transport across these boundaries.
This paper presents a coarse-grained electrodynamic model demonstrating that optimizing the thickness of a carbon-based anchoring layer on helical carbon coil arrays significantly enhances microwave absorption in the 2–18 GHz range by improving impedance matching.
This paper introduces SkeleGen, a symmetry-constrained generative model that expands the discovery of flat-band materials beyond traditional geometric prototypes by generating and validating over 9,000 stable crystal candidates featuring novel, out-of-distribution sublattice motifs.
