This study proposes and demonstrates through micromagnetic simulations and analytical models that magnetic skyrmions can exhibit a net ratchet motion orthogonal to continuously applied surface acoustic sawtooth waves by overcoming pinning centers via a specific strain gradient.
This paper demonstrates the creation of a tunable magnon-polaron cavity by strongly coupling confined phonons in a ZnO surface acoustic wave resonator with finite-wavelength magnons in a YIG film, achieving exceptionally low dissipation rates and observing the first time-domain Rabi-like oscillations in such a hybrid spin-acoustic system.
This paper presents a unified statistical theory of heat conduction in nonuniform media by deriving a causal spatiotemporal kernel via the Zwanzig projection-operator formalism, which microscopically encodes memory, nonlocality, and heterogeneity to seamlessly bridge classical diffusion, hydrodynamic, and quasi-ballistic transport regimes while recovering conventional coefficients as coarse-grained limits.
This paper demonstrates that while Coulomb drag vanishes in two capacitively coupled superconducting nanowires due to exact plasmon cancellation, a finite drag voltage emerges when the passive wire develops a mass gap below the superconductor-insulator transition, as the resulting mass term synchronizes plasmon modes and lifts the cancellation.
This paper investigates the decay dynamics of a transmon qubit coupled to a broadband one-dimensional cavity, using resolvent formalism to identify a transition from Markovian to non-Markovian regimes based on coupling strength and demonstrating how two-photon decay channels significantly influence the system's energy-dependent resonance widths.
This study demonstrates the spectroscopy of up to eight interacting spins in a 2x4 germanium quantum dot array using Ramsey interferometry and adiabatic mapping, successfully reconstructing the many-body energy spectrum and observing the crossover from localization to a chaotic phase.
This paper investigates ballistic electron transport in AB-stacked bilayer graphene, revealing that perfect transmission at discrete energies arises from mode-selective phase-matching cavity resonances within electrostatic barriers, a phenomenon distinct from Fabry-Perot interference and decoupled channel activation.
This paper demonstrates that excitons in twisted MoTe flat Chern bands exhibit giant, momentum-space helical dipole moments driven by Berry curvature, which can be tuned via an external displacement field to induce a Frenkel-to-Wannier transition and facilitate the formation of quadrupolar biexcitons.
This paper demonstrates that trilayer MoSe2 devices with a multi-gate architecture can be electrically reconfigured to transition from single-dot to double-dot transport regimes by tuning the backgate voltage, enabling the study of non-equivalent quantum dots with tunable coupling.
This paper proposes that vacuum fluctuations of a quantized magnetic flux from an LC resonator in a circuit QED environment can mediate long-range attractive interactions between angular momentum states in two-dimensional electron systems, leading to the formation of a tunable, high-temperature chiral pair-density-wave superconducting state.
