The role of non-equilibrium populations in dark exciton formation
Paul Werner, Wiebke Bennecke, Jan Philipp Bange +15
In two-dimensional transition metal dichalcogenide structures, the optical excitation of a bright exciton may be followed by the formation of a plethora of lower energy dark states…
Anomalous topological edge modes in a periodically-driven trimer lattice
