Symmetry-based efficient simulation of higher-order coherences in quantum many-body superradiance

Symmetry-based efficient simulation of higher-order coherences in quantum many-body superradiance Holzinger, Raphael; Rubies-Bigorda, Oriol; Yelin, Susanne F.; Ritsch, Helmut We propose an efficient method to numerically simulate the superradiant emission dynamics of large numbers of quantum emitters in ordered arrays in the presence of long-range dipole-dipole interactions mediated by the vacuum electromagnetic field. Using the spatial symmetries of the system, we rewrite the equations of motio
