- Abstract: We show how to simulate a model of many molecules with both strong coupling
to many vibrational modes and collective coupling to a single photon mode. We
do this by combining process tensor matrix product operator methods with a
mean-field approximation which reduces the dimension of the problem. We analyze
the steady-state of the model under incoherent pumping to determine the
dependence of the polariton lasing threshold on cavity detuning, light-matter
coupling strength, and environmental temperature. Moreover, by measuring
two-time correlations, we study quadratic fluctuations about the mean-field to
calculate the photoluminescence spectrum. Our method enables one to simulate
many-body systems with strong coupling to multiple environments, and to extract
both static and dynamical properties.
