| dc.description | Using the master equation we calculate the contribution of the excited state of a two-level atom to its interacting potential with a perfectly conducting wall at finite temperature. For low temperature, $\hbar ω_0/k_B T = k_0 λ_T\gg 1$, where $ω_0 = k_0 c$ is the transition frequency of the atom and $λ_T$ is the thermal wavelength, we show that this contribution is very small $(\propto e^{-k_0λ_T})$. In the opposite limit $(k_0λ_T \ll 1)$, however, we show that the expression for the interacting potential, for all relevant distance regimes, becomes exactly the same as that for very short distances $(k_0 z \ll 1)$ and with the field in the vacuum state. | |
