This paper demonstrates that the Mpemba effect, where a system initially farther from equilibrium relaxes faster than a closer one, can occur within the linear-response regime of many-body systems through spectral separation in reciprocal systems and non-normal relaxation dynamics in non-reciprocal systems.
This paper identifies temperature-dependent band structure renormalization as a fundamental thermodynamic mechanism that violates the Wiedemann-Franz law in interacting systems by decoupling heat and charge transport, thereby offering a unified framework to probe topological robustness and Fermi liquid instabilities.
ChemFit is a flexible Python framework designed to streamline the parameterization of complex simulation-based models by enabling the definition, composition, and massively concurrent evaluation of heterogeneous objective functions in conjunction with gradient-free optimization algorithms.
This paper proposes a novel cold source field-effect transistor (CSFET) utilizing a type-III aligned 2D WTe/HfS heterostructure to eliminate Schottky barriers, achieving a high on/off ratio of 10 and a sub-thermal subthreshold swing of 41.3 mV/dec through first-principles quantum transport modeling.
This paper proposes a quasi-two-dimensional Su-Schrieffer-Heeger model with complex hopping and spin-orbit coupling that hosts distinct topological phases, including quantum anomalous spin Hall insulators, and supports persistent spin textures within a nontrivial topological framework.
This paper establishes guidelines for interpreting microfocused Brillouin light scattering spectra by analyzing how spin wave dispersion relations and mode profiles shape spectral features in three distinct magnetic materials, demonstrating that accurate interpretation requires exact dispersion and profile data, especially when mode hybridization occurs.
This paper introduces a hybrid analog teleportation-direct transmission protocol that replaces digital error correction with analog feedforward through a noisy quantum channel, demonstrating that while standard quantum teleportation is superior when the channel degrades entanglement, this hybrid approach is optimal otherwise and particularly effective for coherent-state transfer in optical and superconducting microwave systems.
This paper investigates a two-band system with momentum-dependent hybridization between a dispersive and a flat band, demonstrating that the interplay of interband mixing and intraband pairing can create parabolic nodes in the quasiparticle spectrum, leading to a quadratic temperature dependence of superconducting phase stiffness and revealing the system's sensitivity to nonmagnetic disorder through Machida-Shibata resonances.
This study numerically demonstrates that interfacial Dzyaloshinskii-Moriya interaction induces non-reciprocity in strongly coupled trilayer square artificial spin ices, leading to frequency-split edge modes whose interference patterns are governed by the interplay between DMI magnitude, external magnetic fields, and stray fields.
By fabricating SQUIDs from twisted interfaces, researchers detected a phase shift and time-reversal symmetry breaking indicative of chiral superconducting order, while also demonstrating high-temperature flux sensing capabilities that open new avenues for studying unconventional superconductivity.
