A generalized Hydrodynamics, referred to as Mesoscopic Hydro-Thermodynamics, of phonons in semiconductors is presented. It involves the descriptions of the motion of the quasi-particle density and of the energy density. The hydrodynamic equations, wh

In the context of direct imaging of single nanoparticles, we discuss strategies for simulation of the small angle X-ray scattering (SAXS) of nanoparticles, propose a new scalar numerical approach applicable to arbitrary collections of atoms and compa

We report on first experiments of rare gas cluster dynamics and spectroscopy using light from the DESY free electron laser at 13 eV. The energy absorption is found to be very efficient and the clusters fragment completely. Non-linear effects appear a

We discuss strategies for color separation and recombination, regarding 2-color pump-and-probe experiments planned for the DESY XUV FEL Phase 2. We show that efficient handling of the pump and probe components, with good spectral and spatial separati

We give a unified discussion of two different approaches to the design of grazing incidence monochromators with a variable line spacing (VLS) grating for soft X-ray undulator sources. Neither one uses an entrance slit and both work with a fixed posit

Colloidally prepared CdSe and CdSe/ZnS core-shell nanocrystals passivated with trioctylphosphine/trioctylphosphine oxide and hexadecylamine have been studied by photoelectron spectroscopy with tuneable synchrotron radiation. High-resolution spectra o

As one of the first experiments at the free electron laser of the TESLA Test Facility (TTF) the Coulomb explosion of Xenon clusters irradiated with high intensity pulses at a wavelength of 98 nm has been observed. Classical trajectory calculations ha

We made Monte Carlo simulations of the energy distribution and magnetic moment contributions of surface and core sites in a model particle of spherical shape, intended as a simple representation of hematite colloids. We included exchange interactions

We have recorded synchrotron radiation excited photoelectron spectra of free Ne and Ar cluster beams in the valence and inner valence region. Varying the cluster sizes from a few up to some hundred atoms, the development of inelastic energy losses of

We describe photoemission results from pure and Sb-doped SnO2 nanoparticles deposited on gold substrates. Photoelectron spectra with synchrotron radiation were recorded for Sn 3d, Sb 3d and O 1s core levels and valence bands in the 500-1200 eV energy
