Abstract

It is well known that AC Stark shifts have an impact on the dynamics of atoms interacting with a near-resonant quantized single-mode cavity field, which is relevant for single-atom micromasers. In this study, we demonstrate that when the field is in a squeezed coherent state, the micromaser lines are highly sensitive to the squeezing parameter. Furthermore, we show that when considering a superposition of squeezed coherent states with equal amplitude, the displacement of the transition lines depends significantly not only on the squeezing parameter but also on its sign.
