This paper identifies a "fourth-order closure obstruction" in circular kinetic magnetotransport, demonstrating that truncating the angular momentum hierarchy at the stress level neglects a critical back-action from higher Fermi-surface harmonics that generates a fourth-order term in the current eigenvalue, which becomes chiral and can induce Hall sign reversal under magnetic fields.
This paper presents a generalized theoretical framework for Andreev reflection spectroscopy that incorporates spin-dependent anisotropic scattering to accurately interpret spin polarization and conductance in various magnetic materials, thereby resolving limitations of isotropic models and enabling robust spin-polarized current generation for advanced spintronic and quantum technologies.
This paper establishes a complete thermodynamic framework for radiative spin caloritronics by predicting the spin thermal Hall effect in nonreciprocal magneto-optical systems, where longitudinal radiative heat currents generate transverse spin angular momentum accumulation, and demonstrating that this phenomenon and its inverse form an Onsager-Casimir reciprocal pair subject to fundamental thermodynamic bounds.
The study demonstrates that introducing Janus-induced mirror-symmetry breaking in MoSSe/MoS2 bilayers promotes atomic reconstruction into distorted aperiodic patterns, which significantly weakens interlayer coupling and amplifies the twist-angle dependence of thermal conductance by nearly an order of magnitude compared to conventional twisted bilayer MoS2.
This paper proposes an all-optical THz pump-probe spectroscopy and cavity-based protocol that utilizes magnetoelectric coupling to selectively parametrically amplify and detect topological magnon edge states in two-dimensional van der Waals ferromagnets, overcoming the limitations of conventional detection methods.
This paper proposes current cross-correlations as a robust diagnostic tool to verify the true non-locality and stability of poor man's Majorana modes in minimal Kitaev chains, offering a superior alternative to conventional differential conductance spectroscopy.
This paper demonstrates that in a spin Hall bar connected to an external load, Joule dissipation can vanish at the load when it is positioned far beyond the spin-relaxation length, a unique stationary state achieved through the spatial separation of current injection from energy dissipation.
This paper introduces a robust "EigenProbe" formalism based on probe-cavity eigenmodes and nano-gap polaritons to quantitatively describe and accurately predict non-perturbative near-field interactions in optical nanoscopies, thereby enabling the precise inversion of local optical constants and advancing the field toward precision metrology and strong coupling applications.
This paper theoretically demonstrates that a frequency-modulated double quantum dot coupled to a leaking microwave resonator can generate a single-photon flux exhibiting sub-Poissonian statistics, even in the presence of environmental influences like phonons and temperature.
This paper establishes a dimension-reduction framework that reveals nonzero lower bounds on the quantum metric integral in trivial 2D systems by linking them to one-dimensional topological obstructions and higher-order topological invariants, thereby generalizing the fundamental relationship between quantum geometry and topology beyond conventional Chern number constraints.
