This paper demonstrates the phase locking of a Si nuclear spin ensemble in a silicon quantum dot using only internal electronic spin-orbit coupling as a phase reference, thereby enabling coherent control and measurement of nuclear spin dynamics without external microwave fields.
This paper presents a robust methodology for quantifying the intrinsic mechanical quality factor () in high-stress silicon nitride resonators, revealing a systematic thickness-dependent loss in ultra-thin membranes that challenges existing models and is addressed by a new phenomenological framework.
This paper demonstrates that while a mixed Floquet lattice model with two incommensurate drives can realize momentum-resolved Weyl semimetal topology through power transfer, the total real-space response deviates from static Weyl physics and instead follows an effective Rice-Mele pumping structure, highlighting the unique challenges of translating gapless semimetallic phases into driven synthetic dimensions.
This study demonstrates that stacking two trivial quintuple layers from the BiTe family can induce controllable quantum spin Hall phases in van der Waals heterobilayers, where the topological edge states can be switched on or off via external strain and electric fields while remaining robust against interlayer twisting.
This paper introduces a nonperturbative framework for quantizing chiral solitons in interacting quantum spin chains, explicitly constructing their operators to reveal sign-alternating tunneling amplitudes that distinguish half-odd-integer from integer spins and predicting observable signatures in inelastic neutron scattering.
This study demonstrates that operating graphene resonators in a parametric oscillation regime significantly enhances short-term frequency stability compared to Duffing oscillations by leveraging strong nonlinear damping to suppress amplitude-to-frequency noise conversion.
This paper presents a systematic construction of non-Hermitian -root tight-binding lattices derived from graphene and Lieb photonic ring models, demonstrating how their unique spectral features—including exceptional horns, high-order exceptional points, and anomalous Landau level scalings—can be realized experimentally using coupled ring resonators with balanced gain and loss.
This paper demonstrates that bulk plasmons in Weyl metals possess a topological monopole structure with finite vorticity determined by the Fermi surface's Chern number and exhibit distinctive optical properties through selective coupling to linearly polarized light via a quantum geometric dipole moment.
This paper establishes a minimal hydrodynamic framework demonstrating that exciton diffusivity in 2D semiconductors can become effectively negative due to a dynamical instability arising from the nonequilibrium coupling between slow excitons and fast, inertial electron-hole plasma modes.
This paper investigates how electrostatic gating in bilayer graphene creates valley-contrasting kink states that support persistent drift and circulating currents, thereby forming a quasi-one-dimensional channel of orbital magnetization that can be electrically controlled for applications in valleytronics.
