Abstract

It is proposed a new approach in the estimation of quantum fluctuations of the electromagnetic field and Doppler effect using a model formed from two quantum modes of the cavity which propagate in opposite direction. The Doppler effect plays a significant role in the model in which an atom flies through the nodes and anti-nodes of the standing wave. It is shown that if the vacuum Rabi frequency achieves the value of Doppler shift kv, where k is the wave vector and v represents the atomic velocity, then the collective interactive and non-interactive modes of the resonator become connected. The interaction process looks like in the case of two coupled cavities in one of which is placed an atom. The comparison between the proposed approach and existing time dependent coupling model is given. In our model, it is obtained the non-zero value of quantum fluctuations in the nodes of the standing wave during the time in which atom flies through the cavity.
