This paper presents a generalized transmon Hamiltonian for Andreev spin qubits that utilizes the flat-band approximation of the Richardson model to enable exact diagonalization, thereby simultaneously capturing quantum dot physics, Josephson effects, and Coulomb repulsion across all parameter regimes for modeling both static and time-dependent processes.
This paper introduces a machine learning model that extends the Gaussian Approximation Potential to include noncollinear magnetic degrees of freedom, enabling efficient ab initio spin dynamics with high accuracy by leveraging rotational symmetries and adiabatic approximations.
This paper investigates relativistic corrections to the electron magnetic moment operator in systems with spin-orbit coupling, introducing the concept of an "abnormal magnetic moment" to highlight ambiguities in conventional decompositions and challenges to standard orbital magnetization theories, while deriving a Kubo formula for the kinetic magnetoelectric effect rooted in the noncommutation of position and magnetic field derivative operators.
This paper demonstrates that high-quality bilayer graphene/WSe heterostructures exhibit gate-tunable transitions between weak anti-localization and weak localization, providing direct spectroscopic evidence of proximity-induced spin-split valence bands driven by Rashba-type spin-orbit coupling.
This paper demonstrates that high-overtone bulk acoustic wave resonators (HBARs) can be initialized to an ultra-cold quantum ground state with an effective temperature of 25.2 mK, enabling stringent constraints on new physics phenomena such as high-frequency gravitational waves, ultra-light dark matter, and wavefunction collapse mechanisms.
This study demonstrates that exciton-polaritons confined in two-dimensional anisotropic van der Waals materials within an optical microcavity exhibit non-Hermitian topological features, including exceptional points and bulk Fermi arcs, thereby establishing these materials as a versatile platform for exploring non-Hermitian topology and advancing polarization-controlled optical technologies.
This study demonstrates that magnetic field oscillations can effectively tune the non-flat energy landscape to control the formation and evolution of skyrmion lattice domains, thereby overcoming pinning effects to enhance quasi-long-range order in magnetic thin films.
This paper investigates the transient interference dynamics of a spin-1/2 particle in a two-dimensional disordered potential under uniform SU(2) gauge fields, revealing a unique momentum-offset backscattering peak that coexists with a coherent backscattering dip and providing a perturbative framework to explain its buildup, decay, and dephasing time.
This paper employs a coupled electromagnetic dipole formalism to analyze the far-field radiation of bulk, edge, and corner eigenmodes in a finite 2D Su-Schrieffer-Heeger plasmonic lattice, demonstrating how symmetry breaking and out-of-plane dipolar resonances dictate the darkness, Q-factors, and complex radiation patterns of these topological states.
This study utilizes fluctuational electrodynamics and modal analysis to demonstrate that near-field radiative heat transfer between polaritonic SiC, SiN, and SiO2 subwavelength membranes can be significantly enhanced or attenuated by up to 5.1-fold and 2.1-fold, respectively, due to material-loss-dependent corner and edge modes that alter the electromagnetic state density.
