Why the Markov approximation is not valid at low temperatures in the master equation for a two-level atom?

The correlation function for a two-level atom in contact with a reservoir of photons at temperature T is (I'm using natural units): C_R(\tau)\propto PolyGamma[4, 1-i (\tau/\beta)], where...

How can I compute the average photon number in the strongly correlated James-Cummings model?

In Ref. [Thermal Equilibrium in the Jaynes-Cummings Model ] the James-Cummings model is studier in a general way. In particular, Eq. (8) introduces a reservoir-Hamiltonian. The same procedure can...
