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.
This paper demonstrates that deploying a robotic arm for low-volume academic nanofabrication, specifically in Josephson junction resist development, significantly improves process consistency by reducing resistance spread from ~7% with human operators to ~2%.
This paper presents CavOTF, an open-source, parallelized computational package that combines density functional tight-binding with a light-matter Hamiltonian beyond the long-wavelength approximation to simulate on-the-fly vibrational polariton dynamics, demonstrating that while Mulliken charges can approximate linear spectra, they fail to capture non-equilibrium chemical dynamics due to spurious heating.
This paper proposes a driven-dissipative Floquet model using a modulated harmonic oscillator to realize a non-Hermitian synthetic lattice that exhibits directional amplification and frequency conversion through a topological winding number, offering a feasible route for non-Hermitian topological amplification in current quantum technologies.
This paper elucidates the microscopic mechanism of exciton-polariton relaxation following upper polariton excitation, revealing a two-step process involving vertical inter-band transition and phonon-induced Fröhlich scattering, while demonstrating that finite material thickness significantly suppresses intraband scattering due to phonon-fluctuation synchronization arising from polaritonic spatial delocalization.
This paper demonstrates that microwave irradiation of Josephson junctions containing Yu-Shiba-Rusinov states, combined with broken particle-hole and inversion symmetries, induces a tunable diode effect characterized by asymmetric critical currents that can vanish entirely for one polarity.
This study systematically investigates the nonlinear photogalvanic effect in AA-, AB-, AAA-, ABA-, and ABC-stacked few-layer graphene using a tight-binding model, revealing that while jerk current is permitted in all structures with tunable spectral properties, shift current emerges exclusively in inversion-symmetry-broken ABA-stacked trilayers, thereby establishing a symmetry-band-field coupling paradigm for designing tunable photodetection and energy-harvesting devices.
