This study provides direct experimental evidence that a photo-launched coherent transverse optical phonon mode, responsible for ferroelectric order in the 2D semiconductor NbOI2, couples exclusively to above-gap electronic transitions, revealing a new mechanism for mediating physical properties in ferroelectric semiconductors.
This paper derives semiclassical equations of motion for wave-packets in non-Hermitian topological systems using a complex Berry phase formalism, revealing that complex chirality induces anomalous velocity and force, and proposes a non-Hermitian optical chiral cavity as an experimental platform to realize these effects.
This paper demonstrates that Newton polygons and tropical geometry provide an effective analytical framework for identifying and characterizing the order and anisotropy of Liouvillian exceptional points in open quantum systems, as validated through dissipative spin and superconducting qubit models.
This study demonstrates robust and reversible electric-current control of the anomalous Hall effect in a WTe2/Fe3GeTe2 heterostructure, where a charge current in WTe2 induces an out-of-plane magnetization via the Berry-curvature dipole that modulates the adjacent ferromagnet's properties through the inverse magnetic proximity effect.
This study utilizes magnetic quantum oscillation measurements to map the three-dimensional bulk order parameter of CrSb, revealing a unique -wave altermagnetic symmetry characterized by an exchange splitting profile analogous to the real spherical harmonic.
Despite the expectation that the domain-wall network in magic-angle helical trilayer graphene would prevent well-quantized transport due to gapless modes, researchers observed a robust field-induced Chern gap with that enables quantized Hall resistance, driven by a valley-selective topological transition that gapped the domain boundaries.
This paper demonstrates that centrosymmetric collinear altermagnets can host hidden quantum frustration manifested as equilibrium spin current loops and vortex-antivortex pairs in magnon correlations, driven by a symmetry-allowed staggered Dzyaloshinskii-Moriya coupling despite the absence of classical non-collinearity.
This paper introduces an iterative multiphysics framework that reveals optically induced thermal runaway in VO2 nanostructures, demonstrating how illumination wavelength, ambient temperature, and substrate properties govern the switching threshold to enable advanced design principles for active metasurfaces and neuromorphic photonic devices.
This paper demonstrates that sub-terahertz optical spectroscopy can selectively probe and fingerprint composite fermion edge states in fractional quantum Hall systems by revealing interaction-induced mass-dependent absorption peaks that arise from edge-specific symmetry breaking.
This paper demonstrates that long-range radiative coupling within a passive reciprocal chiral medium induces a non-Hermitian skin effect in an electric dipole chain, characterized by degenerate boundary-localized modes with a unique profile combining an exponential decay and a long-range algebraic tail.
