Population dynamics of excited atoms in non-Markovian environments at zero and finite temperature
Zou Hong-Mei†, Fang Mao-Fa
       
In Ohmic reservoirs with a Lorentz–Drude cutoff function, the population of the atomic excited state versus γ 0 t for different temperatures. (a) T = 0; (b) k B T / ħ ω 0 = 10.
