摘要
运用 Pegg- Barnett的厄米相位公式 ,研究了 J- C模型中原子质心运动和场模结构对场相位动力学的影响。在未考虑原子质心运动和考虑原子质心运动两种情况下 ,分别给出了场相位概率分布和相位涨落随时间的变化规律 ,并比较了两种情况下的场相位动力学。结果表明 :原子质心运动导致场相位动力学的周期性演化 ,场模结构参数决定其周期的大小。
The effects of the motion of atomic mass centre and field mode structure on the dynamics of the field phase in the Jaynes Cummings model are discussed by means of the Hermitian phase formulas of Pegg and Barnett. The time evolutions of the phase probability and the phase fluctuation, with the motion of atomic mass centre neglected and the motion not neglected, respectively, is derived. Under the two conditions, the dynamics of the field phase are compared. The results show that the motion of atomic mass centre leads to the periodic evolution of the dynamics of the field phase and this period depends on the field mode structure parameter.
