This paper introduces RESOLUTE, a novel Ramsey correlation spectroscopy protocol utilizing phase cycling and population imbalance storage that extends effective coherence time beyond the standard limit, enabling the detection of low-frequency signals such as C nuclear spin precession in regimes previously inaccessible to single quantum sensors.
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 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 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 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 derives vorticity-induced effects on Nambu-Goldstone modes in chiral perturbation theory by treating vorticity as an axial-vector field within the Wess-Zumino-Witten framework, resulting in new contributions such as vorticity-induced currents, magnetic-field-induced angular momentum, and modified photon-pion couplings in the presence of electromagnetic fields and finite chemical potentials.
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.
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 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.
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 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 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.
This paper establishes a primitive-cell-resolved crystallography framework that accurately decodes general non-aligned moiré bilayer geometries from imaging by introducing a complete descriptor set and a hybrid workflow, thereby correcting previous assumptions about supercell sizes and enabling precise reconstruction of buried layers for quantum system engineering.
This paper proposes a scheme for universal all-electrical single-qubit control in tilted Dirac-Weyl semimetals by utilizing smooth electrostatic barriers in a quantum point contact geometry to generate tunable valley-dependent phase shifts, achieving near-unit transmission and femtosecond gate times.
