This paper proposes quantum capacitance as a novel equilibrium probe for detecting non-Hermitian physics in Dirac materials, demonstrating that in the weakly non-Hermitian regime, the quantum capacitance exhibits a universal divergence and Landau-level collapse as the system approaches an exceptional point due to hopping imbalance.
This paper predicts that collective quantum superradiance in neuroprotein architectures, such as microtubules, actin filaments, and amyloid fibrils, enhances quantum yields and robustly dissipates high-energy UV photons even under significant thermal disorder, suggesting a potential quantum mechanism for neuroprotection in pathological conditions like Alzheimer's disease.
This paper demonstrates that quantum transport in a biased tight-binding lattice with weak decoherence transitions from a ballistic Landauer regime to a diffusive Esaki-Tsu regime as the tilt increases, with the crossover occurring when the Wannier-Stark localization length matches the lattice size.
This study demonstrates that the ferromagnetic resonance dynamics in -FeO/NiFe heterostructures can be precisely and tunably modulated by manipulating interfacial exchange coupling through variations in temperature, magnetic field, and crystal orientation, offering a pathway for advanced, temperature-responsive spintronic devices.
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 the presence of edge states in a finite lattice can amplify the effects of weak decoherence on fermionic transport by orders of magnitude, making them detectable even when they would otherwise be undetectable in a standard ballistic system.
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 presents a numerically efficient framework based on a Dyson scattering equation and quasinormal modes to calculate the scattered electromagnetic Green's function for systems of multiple coupled optical resonators with finite retardation, avoiding complex nested integrals while maintaining high accuracy.
