This paper establishes a universal framework linking spectral winding topology, fractal structures, and defect-localized states in arbitrary-dimensional non-Hermitian lattices, demonstrating that such states emerge only when the winding number exceeds a defect-size-dependent threshold and exhibit amplified responses under external driving.
This paper demonstrates a thermal analog of the Corbino effect in nonreciprocal many-body systems, showing that an external magnetic field bends the Poynting vector in a radial temperature gradient to generate a tangential heat flux, a phenomenon with potential applications in nanoscale thermal management and energy conversion.
This study reveals that Sondheimer oscillations in cadmium single crystals are governed by a scalable quantum mechanism arising from the commensurability between Landau quantization and the thickness-induced discretization of momentum, a phenomenon absent in copper and distinct from traditional semiclassical explanations.
This study reports the observation of coherent Aharonov-Bohm interference in high-mobility bilayer graphene at even-denominator fractional quantum Hall states, revealing oscillation periods consistent with quasiparticles while demonstrating that controlled deviations in filling factor induce phase shifts confirming the presence of fundamental non-Abelian anyons.
Using diagrammatic Monte Carlo with combinatorial summation, this study demonstrates that Feynman's diagrammatic expansion applied to fundamental electronic degrees of freedom can reliably describe the emergence of fractional quantum Hall states, specifically confirming the incompressible 1/3-filled state and the pseudogapped behavior at 1/2-filling in the thermodynamic limit.
This paper demonstrates that analog quantum teleportation protocols, which utilize noisy quantum channels instead of classical communication, outperform digital protocols if and only if the channel preserves entanglement, offering an optimal solution for intermediate-noise scenarios like cryogenic microwave links.
This paper proves that while non-reciprocal electromagnetic systems in global thermal equilibrium can sustain a non-zero, divergence-free mean Poynting vector (persistent energy current), this phenomenon cannot be detected through out-of-equilibrium heat transfer measurements.
This study reveals that weakly coupled non-Hermitian Hatano-Nelson chains under Möbius boundary conditions exhibit a unique coexistence of skin effect and scale-free localization, where eigenstate localization characteristics can exchange between chains depending on their eigenenergies due to critical behaviors enhanced by the boundary conditions.
This study provides systematic experimental evidence and a theoretical framework demonstrating the tunable coexistence of current-induced spin polarization and orbital magnetization in trigonal tellurium, thereby establishing a pathway for advancing orbitronics and spintronics in chiral crystals.
This paper establishes a general time-dependent framework for many-body quantum geometry by treating external fields as coordinates on the space of density matrices, utilizing the Bures distance to derive a generalized metric and connection that unify linear response theory and reveal how higher-order correlation functions probe nonlinear geometric structures.
