First-principles Newns-Anderson Hamiltonian Construction for Chemisorbed Hydrogen at Metal Surfaces
Nils Hertl, Zsuszanna Koczor-Benda, Reinhard J. Maurer
The Newns-Anderson Hamiltonian is widely used to describe adsorption at gas-solid interfaces, yet its construction typically relies on simplifying assumptions such as constant coup…
Mode selectivity in electron promoted vibrational relaxation of chemisorbed hydrogen on molybdenum and tungsten surfaces
Nils Hertl, Connor L. Box, Reinhard J. Maurer
Electron-phonon coupling in atoms and molecules adsorbed at metal surfaces gives rise to finite vibrational linewidths in infrared or electron energy loss spectra. When it is the d…
A Haldane-Anderson Hamiltonian Model for Hyperthermal Hydrogen Scattering from a Semiconductor Surface
Xuexun Lu, Nils Hertl, Sara Oregioni +5
Collisions of atoms and molecules with metal surfaces create electronic excitations in the metal, leading to nonadiabatic energy dissipation, inelastic scattering, and sticking. Mi…
Nonadiabatic reactive scattering of hydrogen on different surface facets of copper
Wojciech G. Stark, Connor L. Box, Matthias Sachs +2
Dissociative chemisorption is a key process in hydrogen-metal surface chemistry, where nonadiabatic effects due to low-lying electron-hole-pair excitations may affect reaction outc…
Machine Learning and Data-Driven Methods in Computational Surface and Interface Science
Lukas Hörmann, Wojciech G. Stark, Reinhard J. Maurer
Nanoscale design of surfaces and interfaces is essential for modern technologies like organic LEDs, batteries, fuel cells, superlubricating surfaces, and heterogeneous catalysis. H…
Capturing non-equilibrium electron dynamics in metals accurately and efficiently
M. Uehlein, H. T. Snowden, C. Seibel +4
The simulation of non-equilibrium electron distributions is essential for capturing light-metal interactions and therefore the study of photoabsorption, photocatalysis, laser ablat…
