双模SU(1,1)猫态与级联三能级原子的粒子布居相干俘获

TWO-MODE SU(1,1) SCHR?DINGER CAT STATES AND ATOMIC COHERENT POPULATION TRAPPING IN A CASCADE THREE-LEVEL SYSTEM

研究了双模相干光场与级联三能级原子的相互作用 ,结果表明 ,在简并双光子过程中 ,使原子发生布居相干俘获的俘获光场为双模SU( 1,1)薛定谔猫态 。

We have studied atomic coherent population trapping in a cascade three\|level atom interacting with a two\|mode quantized field mediated by two\|photon processes. The states of the field trapping the atom are obtained, which are two\|mode \%SU(\%1,1) Schrdinger cat states, and the nonclassical properties of these states are discussed.
