Deriving Energy-Level Gap of a System in Presence of a Kerr-like Medium by Virtue of Invariant Eigen-operator Method
Weijun Gui, JIA-ZHANG GUI, Tang Gang
In this paper, we find the invariant eigen-operators (IEOs) and the energy-level gap of a system with a two-level atom interacting with single mode cavity field through multi-photon transition in the presence of a Kerr-like medium. From this work, one can see that the IEO method in many cases is simpler and easier on obtaining the energy-level gap formula than the usual way.
