Hamiltonian learning reveals optoelectronic mechanisms across thermodynamic state space in soft semiconductors

The paper introduces FLOW-OTTER, a modular framework that automates the integration of machine-learning force fields and Hamiltonian models to predict and interpret the temperature- and pressure-dependent optoelectronic mechanisms of soft semiconductors like halide perovskites directly from first-principles data.

Equation of state and transport coefficients of warm dense aluminum from mixed deterministic-stochastic density functional theory

Using mixed deterministic-stochastic finite-temperature density functional theory, this study computes the equation of state and transport coefficients of warm dense aluminum up to 1000 eV, revealing significant deviations from existing model-based predictions that offer critical corrections for radiation-hydrodynamics simulations.

Unified description of exciton, phonon and plasmon dispersions in 2D materials from an optical conductivity approximation

This paper introduces the optical conductivity approximation (OCA), a unified framework that accurately describes the linear low-momentum dispersions of excitons, phonons, and plasmons in 2D materials by leveraging q=0 optical conductivity to reveal that these behaviors stem primarily from the 2D macroscopic Coulomb interaction rather than band structure details.

Spin-Polarized Magnetic Metal Electrodes for Magnetic Tunnel Junctions

This Perspective reviews diverse magnetic metal electrode materials for magnetic tunnel junctions, arguing that effective spin polarization is a complex, interface-resolved transport property rather than a simple bulk scalar, and outlines strategies to harness emerging magnetic orders like altermagnets for robust, electrically addressable spintronic applications.

Subnanometer thermodynamic overlayers on bimetallic nanoparticles

This study reveals that bimetallic nanoparticles, exemplified by Au-Rh systems, can form thermodynamically controlled subnanometer "shell-dimer" overlayers driven by elemental immiscibility and lattice mismatch, where a delicate balance of surface, interfacial, and strain energies dictates the stability and atomic-scale structure of the overlayer.
