介于数态和相干态之间的态插值及其与原子系统的相互作用

States interpolating between number and coherent states and their interaction with atomic systems

Hongchen Fu, Yinqi Feng, A. I. Solomon

摘要:

利用二项式态的本征值定义,我们构造了新的中数相干态,它们在两种不同的极限下分别约化为数态和相干态。我们揭示了这些中间态与加光子相干态的联系,并详细研究了它们的非经典性质和准几率分布。值得注意的是,这些介于相干态和数态之间的新态都不表现出压缩,但它们仍然是压缩态。提出了一种产生这些状态的方案。我们还在双光子Jaynes-Cummings模型的框架下研究了这些态与原子系统的相互作用,描述了原子系统在纯Rabi振荡和双光子回复模式之间的响应,并研究了场的可观测量,如光子数分布、熵和Q函数。

英文摘要:

Using the eigenvalue definition of binomial states we construct new intermediate number-coherent states which reduce to number and coherent states in two different limits. We reveal the connection of these intermediate states with photon-added coherent states and investigate their non-classical properties and quasi-probability distributions in detail. It is of interest to note that these new states, which interpolate between coherent states and number states, neither of which exhibit squeezing, are nevertheless squeezed states. A scheme to produce these states is proposed. We also study the interaction of these states with atomic systems in the framework of the two-photon Jaynes-Cummings model, and describe the response of the atomic system as it varies between the pure Rabi oscillation and the collapse-revival mode and investigate field observables such as photon number distribution, entropy and the Q-function.
