Open Quantum System Theory of Muon Spin Relaxation in Materials

This paper presents a non-Markovian open quantum system theory for muon spin relaxation using a Schwinger-Keldysh influence-functional formulation to derive a spin stochastic equation with colored fluctuations and memory effects, enabling a quantitative global analysis of μ\muSR spectra in materials like Li0.73CoO2\mathrm{Li}_{0.73}\mathrm{CoO}_2 that goes beyond standard strong-collision approximations.

Field-induced spin-flip and spin-flop transitions in NdFeO3

This study demonstrates that applying magnetic fields along the crystallographic c-axis in NdFeO3 induces a complex sequence of spin-reorientation, spin-flop, and spin-flip transitions across a broad temperature range, driven by anisotropic 4f-3d coupling and significantly modified by Nd-sublattice ordering below 8 K.

A Γ\Gamma-valley Moiré Platform for Tunable Square Lattice Hubbard Model

This paper demonstrates that Γ\Gamma-valley twisted square homobilayers offer a highly tunable platform for realizing the square-lattice ttUt-t'-U Hubbard model, where an interlayer displacement field breaks emergent layer-exchange symmetry to enable wide-range experimental control over the effective hopping ratio t/tt'/t.

Ultrafast near-field imaging of an operating nanolaser using free electrons

This paper demonstrates a breakthrough in characterizing operating nanowire lasers by using synchronous electron and photon spectroscopies to overcome the diffraction limit, enabling the nanometer-scale, sub-picosecond mapping of near-field dynamics and the quantification of stimulated photon populations to reveal complex cavity modes and material heterogeneity effects.

Comment on 'Observation of Shapiro Steps in the Charge Density Wave State Induced by Strain on a Piezoelectric Substrate'

This paper comments on a 2025 study by Fujiwara et al. that provides clear evidence of charge density wave synchronization in NbSe3 nanowires through the observation of Shapiro steps on I-V curves when driven by resonant surface acoustic waves generated on a piezoelectric substrate.

Experimental Insights into the Limiting Mechanism of Vacancy Transport in Sodium Metal Anodes for Solid State Batteries

This study identifies that the critical limiting mechanism for vacancy transport in sodium metal anodes of solid-state batteries is interfacial thermodynamics rather than bulk diffusion, as evidenced by activation energies significantly higher than bulk migration values and a reduction in these energies upon introducing a sodiophilic tin-sodium alloy interlayer.
