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 for quantum state transfer that replaces classical communication with analog feedforward through a noisy channel, demonstrating that this approach outperforms standard quantum teleportation when the channel does not reduce the entanglement of the resource state.
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.
This paper experimentally demonstrates coherent perfect absorption of anti-modes in an indirectly coupled magnon-polariton system, revealing that the effective decay rate governs spectral amplitude while enabling magnetically tunable, frequency-selective microwave absorption.
This paper introduces and theoretically validates "persistent altermagnetic spin polarization" (PASP), a robust, mirror-symmetry-protected collinear spin texture in altermagnetic materials that persists despite spin-orbit coupling and enables switchable, high-efficiency spin-filtering for next-generation all-altermagnetic memory and transistor devices.
By combining mechanical strain with ultrafast laser pulses and x-ray scattering, researchers discovered a hidden polar phase in quantum paraelectric SrTiO3 characterized by nanoscale polarization modulations rather than conventional homogeneous ferroelectricity, offering a new explanation for its unique behavior.
This paper proposes that measuring quantum inductance in Majorana nanowires provides a critical, phase-sensitive probe to distinguish genuine topological fermion-parity switches from disorder-induced mimics, thereby offering a robust method to confirm the existence of Majorana zero modes when combined with quantum capacitance measurements.
This paper resolves conflicting experimental observations of the anomalous Hall effect in MnTe thin films by demonstrating that surface states, rather than the bulk, dominate the effect and that its sign can be engineered through interface design and crystal termination.
This paper presents a phenomenological resistively-shunted junction model demonstrating that bias-dependent peaks in differential resistance can suppress odd-numbered Shapiro steps in conventional Josephson junctions, offering an alternative explanation for this phenomenon often attributed to Majorana zero modes.
This paper reports the first direct observation of double-dome superconductivity in magic-angle twisted trilayer graphene, where the suppression of superconductivity near a specific filling factor reveals a distinct phase transition and supports the existence of an unconventional superconducting order parameter linked to an incommensurate Kekulé spiral state.
This paper demonstrates that broken intrinsic symmetry in a synthetic ferrimagnet induces a strong coupling between acoustic and optical magnon modes, resulting in a large avoided level-crossing gap of 3.9 GHz that is tunable via interlayer exchange interaction and exceeds typical coupling strengths in other magnonic hybrid systems.
Using angle-resolved photoemission spectroscopy, researchers successfully created, detected, and controlled quasi-steady dark excitons in doped SnSe2, revealing a novel anisotropic excitonic gap phase that extends the study of dark excitons from ultrafast timescales to quasi-equilibrium conditions.
This paper demonstrates that near-field thermal transport in nanoparticles can be dynamically modulated through selective surface mode excitation by tuning the distance between reflectors and nanoparticles within a multilayer cavity, offering a novel mechanism for nanoscale thermal management and sensing.
