First-principles prediction of chiral-phonon-induced orbital accumulation

Using first-principles calculations, this study demonstrates that coherent chiral lattice motion in metals induces significant orbital accumulation and a smaller spin accumulation, revealing that the response is primarily governed by orbital character and electron-phonon coupling rather than spin-orbit coupling alone, thereby identifying light transition metals as promising platforms for chiral-phonon-driven orbitronics.

Scale-Dependent Input Representation and Confidence Estimation for LLMs in Materials Property Prediction

This study demonstrates that optimal input representations for materials property prediction depend on LLM scale, with compact formats suiting smaller models and detailed descriptions benefiting larger ones, while establishing mean negative log-likelihood as an effective, training-free confidence metric for fine-tuned models.

Enhanced Valley Polarization via Nonlinear Cascaded Quantum-Geometric Selection Rules

This paper demonstrates that a doubly resonant cascaded nonlinear pathway mediated by a real intermediate state significantly enhances high-lying valley polarization in transition-metal dichalcogenides, offering new perspectives for ultrafast valleytronics by extending quantum-geometric selection rules to the nonlinear regime.

Beyond lead halide perovskites: visible light photovoltaics with phase engineered bismuth-based oxide double-perovskites, Bi2MCrO6 (M = Fe, Mn)

This study reports the optoelectronic characterization of solution-deposited Bi2FeCrO6 and Bi2MnCrO6 thin films as stable, lead-free alternatives for solar cells, demonstrating a 3.56% efficiency for the BMCO-based device and predicting significantly higher performance through future defect control.

Spontaneous Topological Locking and Symmetry Restoration of Meron Lattices in Synthetic Antiferromagnets

This study demonstrates that ultra-weak interlayer antiferromagnetic coupling in synthetic antiferromagnets can spontaneously restore global C4C_4 symmetry and enforce local topological locking of meron lattices, effectively counteracting anisotropy-induced symmetry breaking and structural collapse to stabilize fractional topological textures.

Magneto Transport and Spin Reorientation in Pt Co78Ho22 Heterostructures Near the Sublattice Compensation Temperature

This study investigates the magneto-transport properties of Pt/Co78Ho22/Al heterostructures near the compensation temperature, revealing distinct sign reversals in Hall resistivity and enhanced spin Hall magnetoresistance driven by the interplay of 3d and 4f magnetic sublattices, spin-orbit torque, and potential microscopic phase separation.

Spin order, spin excitations, and RIXS spectra of spin-1/2 tetramer chains

This study employs advanced theoretical methods to map the quantum phase diagram and RIXS spectra of a 1D spin-1/2 Heisenberg tetramer chain, revealing transitions between Haldane and tetramer phases mediated by a deconfined critical state and identifying distinct fractionalized and collective excitations, including quintons, in materials like CuInVO5_5.
