Stationary system of a two-level atom interacting with a single-mode phonon

We use three methods to calculate the ground state energy of the stationary system of a two-level atom interacting with a single-mode phonon. The results indicate that the variational method and the perturbation method are comparable to the exact power series solution in a wide parameter range. This...

Description
Summary:We use three methods to calculate the ground state energy of the stationary system of a two-level atom interacting with a single-mode phonon. The results indicate that the variational method and the perturbation method are comparable to the exact power series solution in a wide parameter range. This might be useful for the time-dependent system.
