This paper resolves the apparent contradiction between Kubo linear response predictions of odd elastic moduli in Hamiltonian systems and energy conservation by demonstrating that the geometry of strain perturbations introduces contact term corrections that reconcile quantum linear response with classical elasticity theory.
This paper proposes a statistical model integrating deep learning techniques, including convolutional and physics-informed neural networks, to predict the dynamic and static properties of magnetic materials with defects, thereby facilitating the discovery of new materials and the determination of minimal defect thresholds for desired magnetic states.
This paper demonstrates a gate-switchable superconducting diode effect in lead nanoscale islands driven into the Coulomb blockade regime, where electron-electron interactions and electrostatic tuning break particle-hole symmetry to induce nonreciprocal Cooper-pair currents without requiring external magnetic fields or complex heterostructures.
This paper presents a computationally efficient theoretical framework based on the Power-Zienau-Woolley Hamiltonian and maximally localized Wannier functions that accurately captures light-matter interactions beyond the electric-dipole approximation in extended systems without requiring finite-order multipole expansions, thereby enabling precise first-principles simulations of spatially structured light dynamics in nanoscale materials.
This paper demonstrates that spin inertia induces massive, potentially chaotic domain wall dynamics that, under finite damping, significantly accelerate ferromagnetic domain wall motion for enhanced racetrack memory performance while also causing domain wall contraction at low driving levels.
This study demonstrates that in gated InAs/GaSb bilayers, Coulomb interactions drive a transition from a quantum spin Hall insulator to a robust excitonic topological order with spontaneous time-reversal symmetry breaking, particularly in the dilute regime or under magnetic fields where triplet electron-hole pairing emerges.
This paper identifies extrinsic population dynamics as the fundamental cause of discrepancies between theoretical and experimental lifetime estimates in multilevel systems, proposing a revised readout protocol and an integrated theory that successfully explains recent spin-valley measurements in bilayer graphene.
This paper introduces topological heavy-tailed networks by constructing a tight-binding model for the Apollonian network with nontrivial gauge fields to reveal the "Apollonian butterfly" spectrum, demonstrating how spectral localizers characterize its topological features as being governed by lower-degree nodes and bridging topological physics with network science for wave control.
This paper theoretically demonstrates that mass asymmetry between two interacting Brownian particles induces a net directional information flow from the heavier to the lighter particle, driven by the heavier particle's superior inertia and memory capacity, with the transfer magnitude scaling logarithmically with the mass ratio.
This paper introduces an analytical parabolic-cylinder approach to model valley-polarized conductance in tilted anisotropic Dirac-Weyl systems, revealing how distinct tilt components govern tunneling and resonance behaviors to identify robust operating conditions for materials like 8-Pmmn borophene and WTe2.
