Enhancing photon generation in cavity through antiresonant terms of the vacuum Rabi coupling

The Rabi model describes the simplest interaction between a two-level system and bosonic mode beyond rotating wave approximation. antiresonant terms that result from this coherent play an important role. In paper, we go approximation even for with vacuum. This leads to ’incoherent’ terms. Using master equation which includes both incoherent terms, numerically compute mean photon number show these enhance generation of number. Moreover study effect detuning it also enhances photons. Finally, generalize our two two-mode systems.
