标题： Nonlinear coherent state generation in the two-photon Jaynes-Cummings model

摘要： 我们证明了双光子 Jaynes-Cummings 模型，在腔量子电动力学或离子阱量子电动力学中可以实现，能够近似产生场的非线性相干态。 我们将这些场的非线性相干态定义为通过提升和降低场算符的$2m$-光子增加或减少的相干态，也称为伦敦相位算符或 Susskind-Glogower 算符。 显示英文摘要

摘要： We show that the two-photon Jaynes-Cummings model, feasible of experimental realization in cavity or ion-trap quantum electrodynamics, can approximately produce nonlinear coherent states of the field. We introduce these nonlinear coherent states of the field as $2m$-photon added or subtracted coherent states in terms of raising and lowering field operators, also known as London phase operators or Susskind-Glogower operators.
