| 摘 要： | 在大失谐条件下,运用密度算符间距研究了一位于相位损耗腔中两个二能级原子与相干光场相互作用系统中原子、光场及系统各量子态随时间的演化规律.讨论了光场的平均光子数和相位损耗对该系统动力学行为的影响.结果表明,相位损耗对光场和系统的密度算符间距均会发生明显影响,但原子的量子态不受损耗的影响.

| Abstract: | The properties of state evolution of the atom, field, and atom-field system in the system of two two-level atoms inside a phase-damping cavity interaction with a coherent field under the condition of large detuning are investigated by using the distance between density operators. The effects of the mean photon number of the filed and the phase damping on the dynamical behaviour in the system are discussed. The results show that the cavity phase damping can change the characters of the distance between density operators of the field and the atom-field system significantly, but the state evolution of the atom is independent of the cavity phase damping. |
