Co-operative atomic effects in a micromaser

Abstract

In this paper, the authors have studied the effect of co-operative atomic interaction in a lossless micromaser. It is shown that transient squeezing can be obtained even in the presence of co-operative atomic effects. However, an increase in the co-operative parameter can completely destroy the squeezing. The steady-state squeezing is never obtained in this system which is due to the fact that trapping states no longer exist in the presence of co-operative effects.
