Microscopic origin of Rashba coupling from first principles: Layer-resolved orbital asymmetry in transition metal dichalcogenides
Miguel Morales Cócera, Marta Prada, Franz Fischer +1
Spin-orbit coupling in two-dimensional materials gives rise to a Rashba spin splitting when inversion and mirror symmetries are broken, yet its microscopic origin and quantitative…

Unconventional bright ground-state excitons in monolayer TiI from first-principles calculations
Franz Fischer, Carl Emil Mørch Nielsen, Marta Prada +1
Based on \textit{ab initio} screened configuration interaction calculations we find that TiI has a bright exciton ground state and identify two key mechanisms that lead to this…

GW effects on the topology of type-II Dirac cones in NiTe, PtSe and PtTe
Franz Fischer, Abderrezak Torche, Marta Prada +1
Many-body correlations are known to be responsible for a broad range of fascinating physical phenomena, introducing corrections that appear elusive at the mean-field level. An exam…
