We propose a semiclassical model for femtosecond laser-induced demagnetization due to
spin-polarized excited electron diffusion in the superdiffusive regime. Our approach treats the …

Femtosecond laser excitation of a ferromagnetic material creates energetic spin-polarized
electrons that have anomalous transport characteristics. We develop a semiclassical theory …

The spin-flip (SF) Eliashberg function is calculated from first principles for ferromagnetic Ni
to accurately establish the contribution of Elliott-Yafet electron-phonon SF scattering to Ni’s …

We demonstrate, to our knowledge, the first bright circularly polarized high-harmonic beams

We report a computational theoretical investigation of electron spin-flip scattering induced by
the electron-phonon interaction in the transition-metal ferromagnets bcc Fe, fcc Co, and fcc …

We present the first materials specific ab initio theory of the magnetization induced by circularly
polarized laser light in metals. Our calculations are based on nonlinear density matrix …

The switching of rare-earth-based ferrimagnets triggered by thermal excitation is investigated
on the basis of an atomistic spin model beyond the rigid-spin approximation, distinguishing …

Ultrafast laser excitation of a metal causes correlated, highly nonequilibrium dynamics of
electronic and ionic degrees of freedom, which are, however, only poorly captured by the …

Transport measurements have revealed several exotic electronic properties of graphene.
The possibility to influence the electronic structure and hence control the conductivity by …

Understanding how the electronic band structure of a ferromagnetic material is modified
during laser-induced demagnetization on femtosecond time scales has been a long-standing …
