Explore the fascinating intersection where quantum materials meet the complexity of everyday environments in the Cond-Mat — Mes-Hall section. This field investigates how tiny particles behave when caught between the orderly world of single atoms and the chaotic nature of bulk matter, revealing the hidden rules that govern electricity, magnetism, and heat in novel substances.
Gist.Science brings these cutting-edge discoveries to you directly from arXiv, the leading repository for physics preprints. We process every new submission in this category as soon as it appears, offering both straightforward, plain-language explanations and deep technical summaries to help researchers and curious minds alike grasp the latest breakthroughs without getting lost in dense equations.
Below are the most recent papers in this dynamic area of condensed matter physics, ready for you to explore.
This paper reports highly gate-tunable, room-temperature nonreciprocal charge transport in dual-gated BiSbTeSe2 topological insulators, attributing the robust signal near the charge neutrality point to inhomogeneous spin-momentum locking in the topological surface states.
This paper predicts a novel 3D quantum Hall effect in Chern vector systems where global topology enforces a robust, dimension-dependent quantized Hall conductance through a collective chiral network, even when individual edge modes are fragile to disorder.
This paper investigates the magnetic-field effects on the K lattice's electronic states using a tight-binding model, revealing a Hofstadter spectrum with geometry-dependent substructures and a unique Landau-level structure featuring a pseudospin-flat branch and relativistic ladders arising from its triple-Dirac cones.
This study demonstrates that in a MoWSe monolayer alloy, a strong in-plane magnetic field induces the darkening of bright excitons by approximately 85% through field-driven level repulsion and population depletion, a phenomenon enabled by alloying which positions the system near a bright-dark crossover with strong magnetic coupling.
This study demonstrates that tailoring the thickness of Fe/-Sn heterostructures leverages long-range magnetic proximity effects to suppress topological surface states at one interface while opening an exchange gap at the other, resulting in a record-high room-temperature inverse Edelstein length of -3.1 nm at a 25 nm thickness.
This paper demonstrates that introducing non-Hermitian substitutional impurities with asymmetric hopping amplitudes in a Su-Schrieffer-Heeger chain provides a deterministic mechanism to actively shift topological phase boundaries and induce disorder-driven universality class transitions, as validated by finite-size scaling and spectral analysis.
This paper experimentally demonstrates and theoretically confirms a novel method for guiding spin waves into a closed circular path within an unbounded ferromagnetic film using a hard magnetic spherical microparticle, thereby overcoming propagation limitations in 2D magnonic circuits.
This paper computes the optical force on a lossless dielectric slab by reconciling Lorentz force and external momentum flux methods, revealing that their general difference arises from the time-dependent electromagnetic momentum stored within the slab, which generates a velocity-dependent force in cavities and resolves the Abraham-Minkowski momentum debate in vacuum environments.
This paper employs non-Hermitian quantum mechanics to parameterize the dynamics of coupled classical diffusion equations for low- and high-energy quasiparticles in superconducting single-photon detectors across one to three spatial dimensions.
This paper proposes that the abrupt increase in quantum oscillation frequencies observed in rhombohedral graphene near superconductivity arises from a transition where inner hole pockets crystallize into an "anticrystal" state rather than collapsing, thereby preserving a larger Fermi contour that supports magnetic-breakdown orbits.
