Electron–ion coupling is a fundamental process in nonequilibrium Warm Dense Matter. It
also plays a central role in governing the states resulting from the interaction of high …

Many fundamental processes of structural changes at surfaces occur on a pico-or
femtosecond timescale. In order to study such ultrafast processes, we have combined …

We use ultrafast electron diffraction to detect the temporal evolution of non-equilibrium
phonons in femtosecond laser-excited ultrathin single-crystalline gold films. From the time …

We performed relativistic ultrafast electron diffraction (UED) measurements of the structural
dynamics of photoexcited gold nanofilms and developed an atomistic model, based on the …

Time-resolved diffuse scattering experiments have gained increasing attention due to their
potential to reveal nonequilibrium dynamics of crystal lattice vibrations with full momentum …

Electron–phonon coupling processes determine electronic transport properties of materials
and are responsible for the transfer of electronic excess energy to the lattice. With …

We apply time-resolved MeV electron diffraction to study the electron-lattice energy
relaxation in thin film Au-insulator heterostructures. Through precise measurements of the …

The time evolution of the Bragg peaks of photo-excited gold nanofilms is measured using
transmission ultrafast electron diffraction (UED) with 3.0 MeV electron pulses and the …

Laser ablation has been widely used for a variety of applications. Since the mechanisms for
ablation are strongly dependent on the photoexcitation level, so called cold material …

Quantum materials are driving a technology revolution in sensing, communication, and
computing, while simultaneously testing many core theories of the past century. Materials …
