摘要

Abstract

Novel photon sources—such as XUV- or X-ray lasers—allow to selectively excite core excitations in materials. We study the response of a simple metal

to the excitation of 2p holes using molecular dynamics simulations. During the lifetime of the holes

the interatomic interactions in the slab are changed; we calculate these using WIEN2k. We find that the melting dynamics after core-hole excitation is dominated by classical electron–phonon dynamics. The effects of the changed potential surface for excited Al atoms occur on the time scale of 100 fs

corresponding to the Debye time of the lattice.
