AQVolt26: High-Temperature r2^2SCAN Halide Dataset for Universal ML Potentials and Solid-State Batteries

The paper introduces AQVolt26, a high-temperature r2^2SCAN dataset of over 320,000 lithium halide configurations, demonstrating that while foundational machine learning potentials provide a strong baseline, their reliability for dynamic screening of solid-state electrolytes critically depends on augmentation with targeted high-temperature data rather than general near-equilibrium relaxation information.

Temperature-dependent Raman spectra of 2H-MoS2 from Machine Learning-driven statistical sampling

This study employs a machine learning-driven statistical sampling approach to calculate the temperature-dependent Raman spectra of crystalline 2H-MoS2, successfully reproducing experimental trends in frequency shifts and linewidths caused by thermal and anharmonic effects to establish a robust framework for future investigations of amorphous molybdenum sulfides.

Evolution from Landau Quantization to Discrete Scale Invariance Revealed by Quantum Oscillations in Topological Materials

This paper reports the observation of a continuous transition from low-field Shubnikov-de Haas oscillations to high-field log-periodic oscillations in the Dirac material HfTe5, demonstrating how vacuum polarization and many-body screening drive the evolution from single-particle Landau quantization to an interaction-induced, discrete scale-invariant energy spectrum.

Nonlinear Magnetic Orbital Hall Effect Induced by Spin-Orbit Coupling

This paper proposes a second-order nonlinear magnetic orbital Hall effect induced by spin-orbit coupling in antiferromagnets, which offers a unified solution for electrical readout of 180° switching in compensated antiferromagnets and electrical writing of perpendicularly magnetized ferromagnets via out-of-plane orbital torque.

Unraveling Intrinsic Thermal Conductivity in Layered Conductive MOF Single Crystals

This study reports the first investigation of intrinsic thermal conductivity in layered conductive metal-organic framework (LCMOF) single crystals, revealing ultralow thermal conductivities (0.075–0.194 W m⁻¹ K⁻¹) along the π–π stacking direction caused by structural disorder and incommensurate modulation, which effectively decouples thermal transport from the high electrical conductivity observed in these materials.

Effective electron coupling to phonon mechanical angular momentum in helical systems

This paper demonstrates that in chiral crystals, mechanical angular momentum (MAM) of phonons can be converted into electronic degrees of freedom via a second-order perturbative Hamiltonian, thereby directly influencing electronic orbital and spin polarizations alongside the previously established crystal angular momentum (CAM) coupling.

Noble-Gas Solubility in Solid and Fluid Metallic Hydrogen

Using ab initio molecular dynamics and free-energy calculations at 500 GPa, this study reveals that while noble gases are insoluble in solid metallic hydrogen due to unfavorable electronic and vibrational contributions, heavier noble gases (Ar, Kr, Xe) become soluble in the liquid phase, offering a microscopic mechanism for noble-gas fractionation in giant-planet interiors.
