Below are the most recent papers in this dynamic area of condensed matter physics, ready for you to explore.
This paper proposes that the surface phonon Hall viscosity in magnetic topological insulators induces a novel interface phonon mode that acts as a circular polarization filter, enabling the selective transmission and manipulation of phonon angular momentum through phenomena like Faraday rotation and mode conversion.
This paper introduces spin-space symmetries to resolve ambiguities in defining -wave magnets, demonstrating through a honeycomb bilayer model that nodal -wave magnets exhibit unique bulk spin conductivity and induce surface -wave magnetism capable of generating a bulk-forbidden Edelstein effect.
This paper reports the discovery of highly stable, spectrally consistent, and polarization-aligned single-photon emitters in as-exfoliated carbon-doped hexagonal boron nitride without post-treatment, offering a scalable platform for integrated quantum photonic circuits.
This paper investigates the quantum Mpemba effect in the spin-boson model, demonstrating that while the effect's visibility in the weak-coupling regime depends on the chosen distance measure, stronger system-bath coupling restores it across measures and reveals a universal geometric structure on the Bloch sphere where rotationally related excited states exhibit relaxation-order inversion.
Using first-principles calculations on monolayer MnPS, this study demonstrates that localized electron polarons can modulate magnetism in 2D materials by locally breaking magnetic symmetry and inducing anisotropic exchange couplings, offering a novel mechanism for atomic-scale control of magnetic textures in spintronic applications.
This study demonstrates that local strain in CdTe/ZnTe quantum dots reorients the spin quantization axis of a single Ni²⁺ ion, thereby modulating hole-ion exchange interactions to enable the spectroscopic resolution of spin-mixed bright and dark exciton transitions under varying magnetic fields.
This paper introduces a phonon-magnon extension to the mumax+ framework that validates three SAW coupling mechanisms and reveals that, contrary to expectations, magneto-rotation coupling—not the dominant magnetoelastic field—drives ferromagnetic resonance in the longitudinal geometry, enabling strong coupling regimes.
This paper demonstrates that on-surface synthesized carbon-based macrocycles composed of [2]triangulene units exhibit strongly entangled quantum spin states governed by Hückel aromaticity rules, revealing non-trivial antiferromagnetic order in even-membered rings and frustrated ground states in odd-membered rings beyond the conventional Heisenberg model.
This paper identifies overdamped gauge phonons, which couple to electronic currents in Dirac materials, as a new microscopic mechanism driving non-Fermi-liquid behavior without requiring proximity to a quantum critical point, thereby offering a promising explanation for anomalous metallic states in systems like twisted bilayer graphene.
This paper reports the fabrication and optical characterization of air-suspended yttrium iron garnet (YIG) photonic crystal nanobeam cavities via focused-ion-beam milling, demonstrating a critical step toward on-chip integration for future coupled photon-phonon-magnon quantum technologies.
