摘要
介绍了单模压缩相干态及其基本性质 ,根据简并V型三能级原子与单模光场的改进型有效哈密顿量 ,通过矩阵方法推导出原子 光场系统的态矢量 提出利用简并V型三能级原子与单模光场的非共振相互作用制备压缩相干态的叠加态的一种新方案 。
The single-mode squeezed coherent states and their fundamental properties are discussed. Based on the modified effective Hamiltonian for the atom-field system, the state of the system is derived by means of matrix. A new scheme is presented to generate superposition of squeezed coherent states through non-resonant of degenerate V-type three-level atoms with single-mode cavity field. Controls of the squeezing direction of single-mode squeezed coherent states in the light field are also discussed.
