Mapping Thermal Conductivity at the Atomic Scale: A Step toward the Thermal Design of Materials

open access: yesphysica status solidi (b), EarlyView.
The site‐projected thermal conductivity method resolves the local thermal conduction contribution per atom by decomposing the Green–Kubo thermal conductivity tensor under the harmonic approximation. It highlights thermally active sites and “thermal defects” within disordered or amorphous materials, enabling spatially resolved insights into atomic‐scale

Magnetic Hopfions as Local Rotations of the Uniform Magnetization Background

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
The Hopf mapping of 3D coordinate space to the unit sphere m2 = 1 in the magnetization space m(r) can be parametrized by some angles. These angles are used to define a local rotation matrix to restore the hopfion magnetization configuration from the uniformly magnetized state for any Hopf indices.
