This paper demonstrates that anisotropic and rotated Fermi surfaces can generate a finite, non-quantized transverse conductivity in the absence of magnetic fields or Berry curvature, offering a symmetry-based mechanism to engineer transverse signals in low-symmetry materials.
This paper demonstrates a gate-tunable analog memcapacitor based on the LaAlO3/SrTiO3 interface that overcomes the fabrication and stability limitations of existing devices by utilizing charge localization in a lateral floating gate to achieve controllable capacitance hysteresis for power-efficient neuromorphic applications.
This paper investigates a non-Hermitian Josephson junction to identify and propose an experimental protocol for detecting a novel supercurrent contribution arising from the phase derivative of Andreev level broadening, demonstrating that this fingerprint of non-Hermiticity can be observed even in the absence of exceptional points.
This paper employs the non-equilibrium Green's function framework to derive analytical formulas for the far-field radiated energy, linear momentum, and angular momentum from metallic thin films, demonstrating how an external magnetic field induces gyrotropy to enable torque radiation and establishing a unified connection between these radiative quantities and generalized Fresnel coefficients.
This study uses Monte Carlo simulations to demonstrate that intrinsic step jamming in nanometer-scale KPZ-like crystal surfaces arises from asymmetric atomic attachment and detachment fluctuations under interface-limited growth, a phenomenon distinct from symmetric thermal effects and analogous to jamming in asymmetric exclusion processes, where the resulting crystal profile shape depends on step geometry: circular steps exhibit a bell-shaped profile during growth and a cup-shaped profile during regression, whereas linear steps display the reverse pattern.
This paper establishes a unified framework connecting non-Hermitian Zeeman quantum geometry, local Dirac-node topology, and measurable transport signatures by demonstrating that the Zeeman quantum geometric tensor decomposes into normal and anomalous sectors, where the latter reveals a novel curvature-flux representation of local topology and distinct linear response scalings.
This study demonstrates that depositing few-layer CrSBr on a gold thin film induces a ferromagnetic ground state through electron transfer and substrate engineering, as confirmed by spin-polarized low energy electron microscopy and supported by density functional theory calculations.
Using segment DMRG on infinite cylinders, this study demonstrates that gate-induced screening in fractional quantum Hall states can bind like-charged anyons into stable molecules across various filling factors and fusion channels by suppressing long-range repulsion and revealing intermediate-range attraction, with significant implications for addition spectra, interferometry, and anyon superconductivity.
This paper establishes a quantitative bulk-boundary correspondence in interacting topological insulators by demonstrating that a gauge-invariant many-body winding number, constructed from Pancharatnam geometric phases, uniquely predicts universal entanglement spectrum degeneracies that scale as with the winding number .
This paper provides non-perturbative arguments and self-consistent Hartree-Fock calculations demonstrating that "self-doped" Wigner crystals, recently observed in rhombohedral graphene, generically emerge from preempted band-inversion transitions between commensurate crystals, a mechanism driven by quantum geometry that establishes their existence in both the -jellium model and rhombohedral pentalayer graphene.
