This paper demonstrates that on a lattice with proper regularization and translational symmetry, massive Dirac fermions exhibit integer-quantized Hall conductivity rather than the half-quantized response associated with the parity anomaly, which is shown to be a property exclusive to massless Dirac fermions.
This paper establishes a general macroscopic formalism to distinguish between Hall and Rashba-Edelstein contributions to spin- and orbital-to-charge conversion in noncentrosymmetric materials, demonstrating through a case study of ferroelectric GeTe that the Rashba-Edelstein effect is the dominant mechanism driving charge current generation.
This paper demonstrates that multi-site mesoscopic quantum Hall circuits with four or more sites exhibit interaction-driven non-Fermi liquid physics and unique quantum-critical points due to higher-order backscattering processes, establishing them as a versatile platform for simulating quantum critical phenomena that can be experimentally controlled and restored to a boundary sine-Gordon description via multichannel channel looping.
This paper presents a symmetry indicator framework that efficiently predicts the topological nature of superlattice-induced minibands with spin-orbit coupling using only the parent material's properties, thereby guiding the design of topological heterostructures even from non-topological starting materials.
This study demonstrates that oxygen and fluorine functionalization, combined with cryogenic temperatures, significantly lowers the sulfur sputtering energy threshold in MoS via the formation of volatile products, thereby widening the ion energy window for selective, damage-controlled chalcogen removal in transition metal dichalcogenide plasma processing.
This paper introduces a data-driven design framework that successfully adapts soft clamping to aperiodic quasicrystal architectures, enabling the creation of nanomechanical resonators with record-high quality factors () and exceptional force sensitivity, thereby establishing a new paradigm beyond traditional periodic structures.
This paper demonstrates that electrostatic gating, interlayer bias, and homogeneous strain offer complementary control over ballistic transport in bilayer graphene junctions by manipulating symmetry constraints, opening tunable gaps, and reshaping angular transmission windows, while identifying a distinct conductance threshold as a key experimental fingerprint of the system's multiband structure.
This paper demonstrates a hybrid-2D excitonic metasurface platform using gate-tunable monolayer WS2 and inverse design to achieve independent, full-range control of both amplitude and phase in the visible spectrum, enabling reconfigurable wavefront shaping for applications like beam steering.
Using large-scale molecular dynamics simulations, this study reveals that physisorbed aluminum and copper nanoparticles exhibit distinct morphological and contact mechanics scaling behaviors that deviate from thermodynamic limits below a critical size of 3–6 nm, whereas larger particles display self-affine surface roughness and approach bulk-like properties.
By combining angle-resolved photoemission spectroscopy and first-principles calculations, this study reveals that the Laves-phase superconductor CsBi2 hosts a dispersionless topological flat band and coupled type-I and type-II saddle points that collectively generate a large electron density of states, offering a novel mechanism for enhancing many-body interactions in three-dimensional systems with strong spin-orbit coupling.
