Our ab initio calculations as well as collaboration with experiment have resulted in two recent publications on CuMnAs properties. In the first one, the finite temperature magnetism and resistivity of antiferromagnetic CuMnAs is described. The second one studies electrical transport properties of bulk tetragonal CuMnAs.

In a short period two of our papers on ultrafast magnetization dynamics due to femtosecond laser pulse has been accepted and published in Phys. Rev B. The first one studies laser-induced dynamics of a magnetic domain walls, while the second one focuses on THz spin waves generation due to superdiffusive spin transport.

A recent paper with contribution by K. Carva, suggested by Phys. Rev. B editor, studies ultrafast nonequilibrium energy flow between electronic and lattice degrees of freedom in crystalline nickel. By combining ab initio calculations with ultrafast diffuse electron scattering, the authors provide a detailed understanding of the complex nonequilibrium energy transfer between electrons and phonons in laser-excited Ni metal.

David Wagenknecht et al. present their fully relativistic density-functional theory treatment of nonzero temperatures. They calculate contributions of phonons and disorder to the temperature-dependent resistivity, anomalous Hall conductivity, and spin-resolved conductivity in ferromagnetic half-Heusler NiMnSb.
