Superradiant to subradiant phase transition in the open system Dicke model: Dark state cascades
Michael Gegg, Alexander Carmele, Andreas Knorr +1
Collectivity in ensembles of atoms gives rise to effects like super- and subradiance. While superradiance is well studied and experimentally accessible, subradiance remains elusive…
