Suppression of collective quantum jumps in Rydberg atoms by collective spontaneous emission

We consider a system of driven, damped Rydberg atoms with dipole-dipole energy shifts which can give rise to a Rydberg blockade when the atoms are driven on resonance and collective quantum jumps when the atoms are driven off resonance. For the damping we consider both independent and collective spontaneous emission. For independent emission a quasiclassical model predicts a bistable steady state and quantum fluctuations drive collective jumps between the two bistable branches. We show that the addition of collective emission to the system leads to a strong suppression of the collective quantum jumps due to a collective emission enhancement
