Effective long-range attraction of moiré excitons under the influence of atomic reconstructions and anisotropic screening
Nils-Erik Schütte, Carl Emil Mørch Nielsen, Niclas Götting +3
The moiré pattern, which emerges due to a relative rotation between two monolayers of transition metal dichalcogenides, features a long lattice period for small twist angles. The…

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…
