This study demonstrates that nonlinear magnetotransport measurements in narrow GaAs channels reveal nonmonotonic differential magnetoresistance signatures of electron pairing, confirming that correlated electron states and heating-induced viscosity changes govern the hydrodynamic flow of viscous electron fluids.
This paper introduces a programmable photonic lattice architecture that utilizes reconfigurable unitary coupling blocks to emulate non-Abelian topological phenomena, including the emergence of protected edge states at Abelian interfaces and the demonstration of non-Abelian braiding operations satisfying Yang-Baxter relations.
This paper presents a quantum response framework for momentum-space gravity in dissipative multiband systems that unifies quantum geometry and equations of motion through interband Weyl transformations, introduces a three-state quantum geometric tensor for classifying nonlinear responses, and identifies a dual quantum geometric drag force as an entropic source for Einstein field equations.
This paper investigates how interatomic Coulomb repulsion and previously overlooked quasi-degenerate states influence a Kitaev-transmon qubit based on double quantum dots, demonstrating that "poor man's Majorana" states persist at sweet spots while revealing a flux-dependent double degeneracy and initial-state sensitivity in the system's microwave spectrum.
This paper proposes a heterostructure of antiferromagnetic MnBiTe and s-wave Fe(Se,Te) superconductor where interlayer sliding-induced ferroelectricity controls the chirality of chiral topological superconductivity by breaking specific symmetries, offering a new pathway for Majorana physics and topological quantum computation.
This study reveals that antiferromagnetic Dirac semimetals possess a hidden "Dirac charge" acting as a source or sink of Berry curvature in a generalized parameter space, which can be experimentally detected through spin-charge-coupled photocurrent responses.
This paper theoretically investigates the tunable dynamical behaviors of antiferromagnetic domain walls under spin-polarized currents, revealing distinct regimes of precessional, propagating, and oscillatory motion depending on current polarization, characterizing their velocity and asymmetric profiles, and discussing the impact of Dzyaloshinskii-Moriya interaction and large induced magnetization for potential experimental detection.
This study demonstrates the first electrically tunable ultrastrong light-matter coupling between a single terahertz complementary split ring resonator and a two-dimensional electron gas in a GaAs quantum well, where gate bias controls electron confinement to modulate the normalized coupling strength from 0.46 to 0.18.
This paper introduces an efficient, first-principles framework that computes photoelectron states as Kohn-Sham scattering solutions to enable accurate, transparent, and widely compatible simulations of angle-resolved photoemission spectroscopy (ARPES), as demonstrated by excellent agreement with experimental data for graphene and WSe.
This paper solves the spin quantum Hall transition on random networks by mapping it to classical percolation and utilizing two-dimensional quantum gravity tools to derive exact critical exponents that satisfy the KPZ relation, thereby confirming the relevance of geometric randomness and supporting numerical simulations of the integer quantum Hall transition.
