Nearly Complete Charge--Spin Conversion via Strain-Eliminated Fermi Pockets in a dd-Wave Altermagnet

This study demonstrates that applying in-plane equibiaxial tensile strain to the room-temperature altermagnet KV2_2Se2_2O eliminates parasitic Fermi pockets, thereby restoring flat-band geometry and achieving a record charge-to-spin conversion efficiency of approximately 96%, which establishes strain engineering as a practical route for high-efficiency spintronic devices.

Critical role of phase-dependent properties in modeling photothermal sintering of LiCoO2 cathodes

This study establishes a multiscale, data-driven framework using an Allegro neural network potential to reveal that phase-dependent thermophysical properties, particularly the strong absorption and distinct thermal conductivity of amorphous LiCoO2, are critical for accurately modeling photothermal sintering and preventing the overestimation of safe operating windows inherent in traditional constant-property models.
