This paper introduces a novel mechanism called exceptional-bound (EB) band engineering that enables system-size-controlled topological transitions in non-Hermitian systems through unique critical scaling near exceptional points, distinct from the non-Hermitian skin effect and applicable to diverse experimental platforms.
This paper proposes that leveraging negative capacitance in engineered structures can invert the natural repulsive Coulomb interaction between electrons into an attractive force, thereby enabling new regimes of Coulomb engineering that could stabilize unconventional correlated phases such as superconductivity.
This paper establishes practical stability bounds for the Generalized Kadanoff-Baym Ansatz (GKBA) in electron-phonon dynamics by identifying parameter regions where the method fails in a Holstein dimer model and demonstrating that coupling to electronic leads can mitigate these instabilities.
This paper theoretically demonstrates that Landau level transitions in monolayer WTe2 induce a giant, tunable photonic spin Hall effect driven by Hall-conductivity-induced Hall angles, enabling nanoscale light manipulation with displacements exceeding 400 times the incident wavelength.
This paper demonstrates that circularly polarized light can induce spin polarization in an achiral metalloporphyrin complex by selectively exciting ring currents to break spin degeneracy, with the resulting transient polarization depending on spin-orbit coupling and Jahn-Teller dephasing rates.
This paper derives a novel theoretical expression for the relaxation time of interacting magnetic nanoparticles by extending Kramers' theory with Tsallis statistics, providing a unified framework that explains both the decrease and increase of relaxation time with dipolar coupling and offers a new interpretation of glassy freezing dynamics through a cut-off temperature.
This paper demonstrates that in planar magnetic multilayers without Dzyaloshinskii-Moriya interaction, interlayer exchange interactions, rather than dipolar effects, are the dominant mechanism driving the frequency shift of nonreciprocal spin-wave dispersion when counterpropagating modes exhibit distinct geometric structures along the thickness.
This paper presents a global method for constructing commensurate supercells in twisted and strained bilayer graphene, revealing that shear strain significantly enhances band narrowing and drives topological transitions, thereby establishing a tunable platform for flat-band and correlated phenomena beyond the magic angle.
This paper establishes a cavity-QED framework connecting hexagonal boron nitride color centers with hyperbolic phonon polaritons, demonstrating how single quantum emitters can serve as on-chip sources to generate, control, and mediate long-range interactions of confined mid-infrared polaritons for advanced quantum optics applications.
This paper demonstrates that irradiating a -wave altermagnet with elliptically polarized light induces a Chern insulating phase, characterized by distinct anomalous thermoelectric and thermal Hall effects that serve as sensitive probes of the system's topological properties.
