Mean excitation numbers due to the anti-rotating term in cavity QED under Lindbladian dephasing
Alexandre V. Dodonov · Physica Scripta · 2012
We study the photon generation from an arbitrary initial state in cavity quantum electrodynamics (QED) due to the combined action of the anti-rotating term present in the Rabi Hamiltonian and Lindblad-type dephasing. We obtain a simple set of differential equations describing this process and deduce useful formulae for the moments of the photon number operator, demonstrating analytically that the average photon number increases linearly with time in the asymptotic limit.
