This paper presents a high-yield, versatile strain platform that enables precise, reversible, and homogeneous uniaxial strain tuning up to ~5.5% in various two-dimensional materials, overcoming previous limitations in strain magnitude, repeatability, and cryogenic performance while also facilitating the study of strain gradients.
This paper numerically investigates Turing patterns on non-fluctuating lattices using Finsler geometry to model mechanical stress, demonstrating that these static systems exhibit stress-induced pattern responses analogous to those observed on fluctuating membranes.
This paper reports the observation of bias-dependent oscillations in photoluminescence, photocurrent, and photo-capacitance within a 0D-2D mixed dimensional heterostructure, revealing large-scale correlated quantum phenomena driven by the competition between coherent and incoherent electron tunneling processes.
Numerical simulations demonstrate that placing polyglycine -sheets and Kevlar molecules on a graphene substrate significantly enhances their thermal stability, allowing hydrogen-bonded structures to retain their shape at temperatures up to 800 K and beyond.
This paper challenges the traditional distinction between metals and insulators by demonstrating that in Berry-curvature-dominated topological insulators, impurity-induced quantum decoherence generates a finite longitudinal conductivity even without charge carriers at the Fermi level, exhibiting unconventional scaling and strange-metal-like temperature dependence.
This review introduces terahertz optorbitronics as a novel ultrafast technique to observe and control non-equilibrium orbital transport in real time, addressing fundamental questions about its propagation mechanisms and potential to enable faster, more energy-efficient information technologies beyond conventional spintronics.
This paper demonstrates that the magneto-tunnel conductance across a junction between a Weyl semimetal and a layered Chern insulator exhibits a universal saturation at high magnetic fields, a phenomenon driven by topological charge pumping rather than magnetic breakdown and independent of microscopic interface details.
The authors experimentally and theoretically demonstrate that negative local and nonlocal voltages in a quasi-one-dimensional aluminum normal-superconducting structure arise from quasiparticle currents at the N-S interface under magnetic fields near the critical temperature, with results consistent across both equilibrium and nonequilibrium superconducting fluctuation models.
This study reveals that singlet-triplet splittings in Ge/SiGe double quantum dots exhibit a surprising, strong dependence on top gate voltages, leading to anomalous photon-assisted tunneling measurements that are successfully modeled by a linear gate-voltage relationship.
This contribution employs a generalized DAOE (Dissipation-Assisted Operator Evolution) algorithm to numerically demonstrate the transition from ballistic to diffusive transport in interacting lattice models, showing that the diffusion constant scales inversely with charge density at low charge densities, and provides a minimal theoretical model that accurately captures these hydrodynamic correlations.
