This paper explains the anomalous negative Fano factor observed in fractional quantum Hall colliders by demonstrating that inter-edge interactions cause anyon beams to fractionalize into uncorrelated components, which dominate in long junctions and reverse the tunneling current sign.
This paper proposes and demonstrates via micromagnetic simulations a compact, programmable spin-wave phase shifter that utilizes the stray field from a moving domain-wall racetrack to modulate the phase of Damon-Eshbach spin waves in an underlying YIG film, offering a promising route for interference-based magnonic circuits and in-memory computing.
This paper proposes a minimal quantum tunneling model incorporating current-induced magnetic fields to explain how chirality-induced spin selectivity achieves near-100% spin polarization and maintains current-direction invariance while respecting Onsager's reciprocity relations.
This paper proposes a theory explaining chirality-induced spin selectivity (CISS) in helical molecules without intrinsic spin-orbit coupling, attributing the effect to a current-induced molecular orbital moment generated by charge circulation in molecular loops that is governed by the molecule's structural handedness.
This paper demonstrates that fragile topological phases, despite lacking protected gapless boundary states, robustly manifest as bulk Dirac cones in two-dimensional materials with time-reversal and twofold rotation symmetry, a prediction confirmed by first-principles calculations in five specific materials.
This study demonstrates that n-doped MoSe2/WS2 heterobilayers within an optical microcavity exhibit strikingly non-monotonic optical nonlinearities and high-velocity trion polaritons with diffusion lengths near 100 microns, driven by Lindhard screening and the absence of electron capture in the Moiré superlattice.
This study demonstrates that engineering the electromagnetic environment of an underdoped YBaCuO thin film using a tunable terahertz cavity enhances superconducting coherence and increases the superfluid weight by boosting phase stiffness, thereby offering a pathway to stabilize superconductivity in correlated systems.
This paper analyzes the transport properties of locally excited quasiparticles in exactly solvable quantum models, revealing that their time-dependent probability distributions exhibit behavior analogous to classical continuous-time random walk models such as Lévy walks and diffusing diffusivity.
This paper reports a comprehensive study of previously unobserved polarized infrared and terahertz photocurrents in bulk tellurium, identifying distinct mechanisms such as the photogalvanic and photon drag effects that can be distinguished by their dependence on polarization, magnetic fields, and radiation frequency, with high-frequency currents driven by direct inter-subband transitions and low-frequency currents by indirect Drude-like absorption.
This study demonstrates that a van der Waals -GeS/-MoS heterojunction leverages the intrinsic in-plane anisotropy of GeS to achieve orientation-dependent, directional charge transport and anisotropic optoelectronic responses, offering a promising pathway for energy-efficient, polarization-sensitive devices.
