This paper reports the reproducible generation of an anomalous, spin-polarized linearly dispersing band with opposite helicity to the topological surface state in Bi-based topological insulator thin films, induced by soft Ar-ion bombardment and annealing.
This paper demonstrates that monitoring particle losses at a single site in a quantum point contact fundamentally alters entanglement dynamics, inducing a transient linear growth with volume-law scaling driven by an emergent bias voltage before eventual decay, a phenomenon captured by a quasiparticle picture and relevant to experimental platforms like ultracold atoms.
This paper presents a spintronic neuromorphic hardware simulation utilizing domain wall dynamics in heavy metal/ferromagnet heterostructures to emulate neurons and quantized synapses, achieving high accuracy on MNIST and Fashion-MNIST datasets while demonstrating the feasibility of sparse, low-memory artificial neural networks.
This paper demonstrates that crystal symmetry enables the generation of pure spin photocurrents in altermagnetic insulators independent of spin-orbit coupling, a phenomenon validated through first-principles calculations on materials like MnTe and BiFeO3.
This study reveals a novel "ferric" topological transition in single-layer Janus MnSeTe driven by higher-order exchange interactions that specifically modify the Bloch point while leaving skyrmion stability largely governed by Dzyaloshinskii-Moriya interaction, establishing the material as a robust platform for 2D skyrmionics with exceptionally high energy barriers.
This paper proposes a generalized Kuramoto-Sivashinsky-type equation based on irradiation-induced anisotropic plastic flow ("ion-hammering") to provide a comprehensive theoretical model that quantitatively and qualitatively explains the formation of nano-patterns on irradiated silicon surfaces across various ion species and energies.
This paper demonstrates through calculations on a FeGeTe/CrGeTe interface that high-order ring-like bimerons and antibimerons possess significantly enhanced, entropy-dominated lifetimes that vastly exceed those of comparable skyrmions, particularly at room temperature.
This paper demonstrates that controlled symmetry breaking in finite-size Mie-resonator arrays can paradoxically enhance optical confinement and Q-factors by strengthening nonlocal coupling pathways, thereby unifying scattering and diffraction theories to enable advanced light manipulation and polarization conversion in nonlocal metasurfaces.
This paper develops a quantization theory for screened plasmons in a periodically modulated graphene sheet on a metallic substrate, demonstrating that the resulting one-dimensional plasmonic crystal supports nontrivial topological bands and edge states that undergo a topological phase transition as modulation increases.
This paper introduces a general "tubular response function" framework to evaluate electrostatic screening in nanotubes with arbitrary electronic properties, demonstrating that metallic carbon nanotubes screen ion interactions almost identically to ideal metals due to quantum confinement and suppressed Friedel oscillations.
