| 摘 要： | 利用相干态正交化展开法，精确求解了非旋波近似下Jaynes-Cummings模型的能谱和动力学性质.与近似下解析解比较发现，在弱耦合和强耦合区近似解析解与数值精确解符合很好，但在中间耦合区符合较差.

| Abstract: | Applying the method of coherent-state orthogonalization expansion，the energy spectra and the dynamical properties of the Jaynes-Cummings model with non-rotating wave approximation are calculated exactly. By comparison with the approximate analytical solutions, it is found that the approximate analytical solutions agree with our numerical exact solutions well both in weak coupling regime and in strong coupling regime, but not so well in intermediate strength coupling regime. |
