spread of fock state distribution and infinite revival time of rabi oscillation in spontaneous emission
In cavity QED for a 2-level atom, the revival time for oscillation b/w the states $\left|\ e\ 0\right\rangle$ and $\left|\ g\ 1\right\rangle$ (absorbing the same photon that is emitted) is said to be ...
Assuming the cavity length is large, can we convert the summation over cavity EM modes to an integral form? In that case is it reasonable to do below conversion? p is the mode number.
