Stationary states of pyramidal molecules coupled to an electromagnetic field below and above critical pressure

Abstract

In this paper, we extend the analysis of stationary states of a nonlinear model of a gas of pyramidal molecules (already discussed in the literature) by including a linear coupling to an external electromagnetic field. It is seen that this results in a shift of the bifurcation point and consequently allows, for appropriate values of Rabi frequency, stable localized stationary solutions below the critical pressure required in the absence of molecule–field coupling.
