Physical exact conditions as regularizers for exchange-correlation in solids and surface chemistry
Johannes Voss
Density functional theory (DFT) often is the method of choice for simulating the electronic properties of extended solids and surfaces from first principles due to a favorable comp…
Atom-Specific Probing of Electron Dynamics in an Atomic Adsorbate by Time-Resolved X-ray Spectroscopy
Simon Schreck, Elias Diesen, Martina Dell'Angela +25
The electronic excitation occurring on adsorbates at ultrafast time scales from optical lasers that initiate surface chemical reactions is still an open question. Here, we report t…
Propulsion of bullet- and cup-shaped nano- and microparticles by traveling ultrasound waves
Johannes Voß, Raphael Wittkowski
The propulsion of colloidal particles via planar traveling ultrasound waves has attracted increasing attention in recent years. A frequently studied type of particles is bullet-sha…
Orientation-dependent propulsion of cone-shaped nano- and microparticles by a traveling ultrasound wave
Johannes Voß, Raphael Wittkowski
Previous studies on ultrasound-propelled nano- and microparticles have considered only systems where the particle orientation is perpendicular to the direction of propagation of th…
Data-driven and constrained optimization of semi-local exchange and non-local correlation functionals for materials and surface chemistry
Kai Trepte, Johannes Voss
Reliable predictions of surface chemical reaction energetics require an accurate description of both chemisorption and physisorption. Here, we present an empirical approach to simu…
Ultrafast adsorbate excitation probed with sub-ps resolution XAS
Elias Diesen, Hsin-Yi Wang, Simon Schreck +24
We use a pump-probe scheme to measure the time evolution of the C K-edge X-ray absorption spectrum (XAS) from CO/Ru(0001) after excitation by an ultrashort high-intensity optical l…
