Spin-valley physics in anomalous thermoelectric responses of the spin-orbit coupled α\alpha-T3T_3 system with broken time-reversal symmetry

This paper demonstrates that the spin-orbit coupled α\alpha-T3T_3 lattice with broken time-reversal symmetry serves as a highly tunable platform for achieving nearly complete spin and valley polarizations in anomalous Hall and Nernst responses, making it a promising candidate for spin-valley caloritronic applications.

Thermodynamics of a biophotomimetic nonreciprocal quantum battery

This paper proposes a biophotomimetic nonreciprocal quantum battery model inspired by bacterial light-harvesting complexes, utilizing collective quantum states and a unimodal cavity to analyze thermodynamic performance, revealing that while strong coupling enhances energy storage capacity, it compromises power output and alters the optimal system size for ergotropy.

Anomalous and Topological Hall Effects in Antiferromagnetic EuSn2As2 Nanostructures

This study investigates magnetotransport in exfoliated EuSn2As2\mathrm{EuSn_{2}As_{2}} nanostructures, revealing that the canted antiferromagnetic state induces an anomalous Hall effect while chiral spin textures give rise to a topological Hall effect, suggesting these phenomena are characteristic features of magnetic 3D topological insulators.

Effect of pulse duration on current-induced selective oxygen migration in high-Tc superconductors

This study demonstrates that reducing the pulse duration in YBCO bridges from milliseconds to nanoseconds significantly increases the onset current for oxygen electromigration by lowering local temperatures, thereby shifting the process toward an athermal regime with important implications for memristor operation and thermomagnetic stability.
