Exact and mean-field analysis of the role of Hubbard interactions on flux driven circular current in a quantum ring

This study employs exact diagonalization and Hartree-Fock mean-field theory to systematically analyze how on-site and extended Hubbard interactions, combined with disorder and electron filling, govern the behavior of persistent circular currents in magnetic flux-threaded quantum rings, revealing distinct monotonic and non-monotonic dependencies on interaction strengths across different filling regimes.

Coupled-wire descriptions of unconventional quantum states in twisted nanostructures

This topical review discusses how coupled-wire descriptions have evolved from a theoretical framework for strongly correlated matter into a highly tunable experimental platform within twisted nanoscale and moiré structures, enabling the continuous exploration and realization of diverse unconventional quantum states, including various topological and fractional phases.

Nonreciprocity Induced Fractional Nonlinear Thouless Pumping

This paper investigates nonlinear Thouless pumping in a non-Hermitian Rice-Mele model, revealing that the interplay between nonlinearity and non-Hermiticity induces fractional topological phases that are naturally explained through the equation of auxiliary eigenvalues, thereby linking nonlinear spectral characteristics to bulk-boundary correspondence.

Nonperturbative Magnetic Orbital Hall Effect in Altermagnets

This paper challenges the prevailing view that nonrelativistic effects in altermagnets are independent of spin-orbit coupling by predicting a giant, nonperturbative magnetic orbital Hall effect that is uniquely allowed in altermagnets, enabling field-free magnetization manipulation and strong room-temperature responses in materials like CrSb and FeSb2.

Optics-microwave entanglement and state teleportation mediated by a cavity magnomechanical system

This paper proposes a cavity magnomechanical system using a micrometer-scale Yttrium Iron Garnet disk to generate steady-state optical-microwave entanglement that enables high-efficiency frequency conversion and achieves a maximum state teleportation fidelity of 0.75 for coherent inputs.

Spin torque driven mode hybridization and band engineering in nanopatterned magnonic crystals

This paper demonstrates that inhomogeneous current-induced spin torque in a nanopatterned Permalloy/heavy metal bilayer with Co nanodots enables dynamic electrical control of spin-wave dispersion through tunable mode hybridization, avoided crossings, and reconfigurable band engineering.

Nonlinear Photonic Tripartite Phase

This paper experimentally demonstrates that Kerr nonlinearity in a quasiperiodic photonic lattice enables state-selective control over a tripartite phase, allowing weak interactions to drive localized states into a coexisting critical window while stronger interactions restore localization.

Nonlinear frequency shift and bistability of magnon-polarons

This study demonstrates that strongly coupled surface acoustic waves and spin waves in a YIG/ZnO heterostructure exhibit a nonlinear frequency shift and bistable foldover behavior driven by cross-shift interactions between counterpropagating magnons, establishing a promising platform for nonlinear magnetoacoustics and wave-based information processing.

Silicate cosmic dust grain collisions in the interstellar medium: A molecular dynamics study

Using molecular dynamics simulations of colliding silicate grains, this study reveals that shattering velocity thresholds are approximately 6 km/s—significantly higher than previously assumed due to a correction in earlier theoretical models—and demonstrates that existing models fail to accurately predict the resulting mass fractions and size distributions of shattered products.

Quantum-metric Bloch oscillations in weakly inhomogeneous electric fields

This paper demonstrates that weakly inhomogeneous electric fields induce a distinct form of Bloch oscillations driven by the quantum metric rather than Berry curvature, resulting in a transport response that can be dominated by scattering-time-dependent effects and illustrated via a tilted Dirac model.
