Electronic non-adiabatic dynamics in enhanced ionization of isotopologues of hydrogen molecular ions from the exact factorization perspective
(Royal Society of Chemistry, 2017-03-28)
It was recently shown that the exact potential driving the electron's dynamics in enhanced ionization of H-2(+) can have large contributions arising from dynamic electron-nuclear correlation, going beyond what any ...
Quantum plasmonics: from jellium models to ab initio calculations
(Walter de Gruyter, 2016-08)
Light-matter interaction in plasmonic nanostructures is often treated within the realm of classical optics. However, recent experimental findings show the need to go beyond the classical models to explain and predict the ...
Spin-texture inversion in the giant Rashba semiconductor BiTeI
(Nature Publishing, 2016-05)
