Geometric phase for Jaynes-Cummings model and interference of atomic states
Andreev V. A. , Klimov A. B., Lerner P. B.
An adiabatic cyclic evolution of the parameters in the model of an interaction of a two-level system with a resonator mode leads to a nontrivial phase shift of a wave function [Berry phase; Proc. R. Soc. A 392,45 (1984) ]. This phase, geometric in nature, could in principle be observed experimentally.
