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 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 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 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 demonstrates fast, scalable readout of silicon double quantum dot spin qubits fabricated with industry-compatible processes, utilizing a second self-aligned gate layer for interdot coupling tunability and gate-based reflectometry for charge sensing and spin readout.
This study provides experimental evidence for local magnetic moments and spin filtering in air-oxidized copper break junctions through low-temperature transport measurements, including magnetotransport and anomalous shot noise analysis interpreted via Kondo physics.
This paper introduces a unified geometric framework based on a generalized time-dependent quantum geometric tensor to derive compact expressions, sum rules, and fundamental bounds for optical, thermoelectric, and thermal transport in clean band insulators, revealing that geometry-driven effects persist even in topologically trivial systems.
Motivated by recent twisted MoTe experiments, this paper develops a disordered interacting edge theory for a fractional topological insulator, revealing distinct conductance phases and an interaction-induced insulating state that demonstrates the insufficiency of two-terminal transport measurements for identifying such systems.
Using time- and angle-resolved photoemission spectroscopy on EuCdAs, the study demonstrates that under high optical photo-doping, bulk plasmons can drive non-equilibrium energy transfer from bulk to surface states to stabilize a long-lived Mahan exciton, revealing a regime where collective modes mediate rather than merely dissipate correlated electronic states.
This paper predicts that exciting magnons in a disordered antiferromagnetic Josephson junction significantly enhances the stationary supercurrent across long junctions, offering a promising mechanism for superconducting spintronics applications.
By combining Corbino-geometry transport experiments in ultraclean GaAs/AlGaAs quantum wells with Hartree--Fock elasticity and Kosterlitz--Thouless--Halperin--Nelson--Young melting theory, this study quantitatively predicts the melting temperatures of quantum Hall bubble crystals, thereby validating the defect-mediated melting framework for strongly interacting electronic solids.
This paper presents a dual-mode mechanical sensing method that utilizes Duffing coefficients and amplitude measurements to eliminate amplitude-to-frequency noise conversion, thereby achieving high stability in micromechanical sensors even when operating beyond the linear regime.
This paper investigates how a strong impurity coupled to the topological boundary of an infinite SSH heterojunction induces bonding and antibonding states within the bulk gap, resulting in a characteristic interference effect in the local density of states that manifests as a transition from a single peak to a double-peak structure.
This paper analytically and numerically demonstrates that a quantum-dot-based Aharonov-Bohm interferometer with superconducting terminals is spectrally equivalent to a simpler side-coupled system, revealing how geometric factors and side-mode competition govern Andreev bound state spectra and induce a Josephson diode effect.
This paper systematically derives a dissipationless quantum kinetic equation for multi-band free fermionic systems using the Moyal product formalism to fully band-diagonalize dynamics and analyze second-order gradient corrections, revealing the critical role of quantum geometric tensors in band-resolved thermodynamics, nonlinear transport, and density-density response functions.
This paper establishes a unified framework for electron- and phonon-driven superconductivity in twisted bilayer graphene, revealing that momentum-space frustration of locally preferred nematic orders can stabilize a chiral ground state with unpaired flat bands at large fillings or weak interactions.
This paper establishes symmetry-based design rules using surface antisymmetry groups to identify specific surface orientations of centrosymmetric -wave altermagnets that enable deterministic electrical switching of the Néel vector via robust interfacial staggered fields and transverse spin currents.
This paper investigates the transition from tomographic to conventional transport in two-dimensional Fermi liquids under a magnetic field by using a numerically exact solution of the linearized Boltzmann equation to demonstrate that a critical magnetic field causes one of two diffusive tomographic collective modes to disappear, leaving a remaining mode that becomes increasingly hydrodynamic at higher fields.

This paper investigates how multi-mode interactions in driven Josephson junction chain cavities degrade internal coherence and shape steady states, revealing that while non-resonant processes dominate equilibrium decay, weak driving enhances resonant scattering to produce observable linewidth signatures and a distinct non-equilibrium steady state.
