This paper theoretically demonstrates that the magnetic Weyl semimetal Co3Sn2S2 exhibits a switchable surface linear photogalvanic effect driven by extrinsic contributions from Fermi-arc states, which can be controlled by magnetization flipping and offers a promising platform for symmetry-controlled optoelectronic applications.
This paper demonstrates that the unique Hermitian ordering of the Dirac Hamiltonian with spatially varying mass, required by probability-current conservation, introduces a logarithmic-gradient term that acts as an emergent geometric background, leading to observable, mode-dependent spectral shifts in compact geometries.
This paper develops an open quantum theory demonstrating that shot noise in dissipative chiral transport is governed by a competition between occupancy distribution and particle-number fluctuations, leading to noise suppression, sign-reversed inter-channel correlations, and a proposed method to experimentally reconstruct hidden occupancy distributions from noise cumulants.
This paper proposes a superconducting circuit architecture utilizing Fourier-engineered Josephson potentials to create "fraxon" states that naturally encode protected qudits, offering a leakage-resistant platform for quantum computing beyond the standard qubit paradigm.
This study reveals that in a non-Hermitian quasiperiodic Su-Schrieffer-Heeger chain with Rashba spin-orbit coupling, increasing non-Hermiticity induces a re-entrant localization transition and a concurrent real-complex-real spectral evolution, where finite spin-dependent hopping splits the spectral loops into four distinct spin-resolved branches with unique topological winding numbers.
This study demonstrates that focused electron beam induced deposition (FEBID) of cobalt and iron nanowires results in reduced metal content and magnetic induction at oblique growth angles due to non-uniform growth dynamics, but these variations can be mitigated by optimizing beam parameters such as using low voltage and high current to fabricate structures with consistent composition across angles from 0° to 60°.
This paper demonstrates that embedding gold nanodisk arrays into van der Waals heterostructures with optimized layer ordering and encapsulation mitigates strain and contamination-induced degradation, thereby enabling the realization of high-quality, homogeneous large-area polariton lattices for applications ranging from polarization control to topological polaritonics.
This paper theoretically demonstrates that under strong Knight fields from photoexcited electrons, resonant optical cooling of nuclear spins in semiconductors can generate significant Overhauser fields that substantially alter the magnetic-field dependence of carrier spin polarization observed in the Hanle effect.
This study demonstrates that current-induced magneto-optical Kerr effect (MOKE) in BiSb alloys serves as a powerful probe for identifying Dirac carriers, evidenced by a signal magnitude exceeding that of transition metals and a distinct scaling relationship with resistivity and mobility that aligns with Dirac electron models rather than conventional parabolic band theories.
This paper proposes that impurity-induced geometric correlations within a Landau level generate fractional energy sublevels and the odd-denominator hierarchy of fractional quantum Hall states through coherent coupling of cyclotron orbits, offering a new organizing principle that explains observed sequences and predicts stability dependent on impurity geometry.
