Geometric Phase in a Generalized Λ-type Jaynes-Cummings Model with Imaginary Photon Process
Jiao Zhi-Yong
By using the Lewis Riesenfeld invariant theory,we have studied the dynamical and the geometric phases in a generalized time-dependent Λ-type Jaynes-Cummings model with imaginary photon process.We find that the geometric phases in a cycle case have nothing to do with the frequency of the photon field,the coupling coefficient between photons and atoms,and the atom transition frequency.If we use the more accuracy device,the geometric phase in the imaginary photon process may be observed,and the geometric phases in this process have the observable physical effect.
