| 1. | It is generally believed that the incoherent pump destroys cpt 一般人们认为,非相干泵浦总是破坏相干捕获效应。 |
| 2. | Next we consider the preservation of cpt by quantum interference of incoherent pump processes 其次考虑非相干泵浦诱导的量子干涉保护相干捕获。 |
| 3. | It has been shown that at the heart of various quantum coherence effects lies cpt 业已表明,在各类量子相干效应中,相干捕获是一种基础的效应。 |
| 4. | This kind of coherent trapping leads maximal atomic coherence , which characterizes ultralarge index of refraction and vanishing absorption 这样的相干捕获导致最大的原子相干,就对应超大折射率和消失的吸收。 |
| 5. | When the polarization direction of the incoherent field and the amplitude and phase of the applied coherent fields satisfy certain conditions , the coherent trapping effect is maintained 非相干泵浦产生的量子干涉在一定条件下可以保护相干布居捕获。我们获得产生相干捕获的条件,找到由两基态构成的暗态和亮态。 |
| 6. | In this paper we have predicted two kinds of new quantum coherence effects . one is the strong - field index enhancement via selective population trapping of dressed states and the other is the preservation of the coherent population trapping ( cpt ) is by quantum interference of incoherent pump processes 本文提出了两类新的原子相干效应,一是利用选择性修饰态捕获产生强场折射率增强,二是非相干泵浦诱导的量子干涉保护相干捕获。 |
| 7. | We have separated the dark state a nd bright state , which are both the superposition states of the ground states . between the dark and bright states there is a unidirectional pathway of population transfer from the bright to dark state . as a consequence , the population transfer leads to cpt 在暗态和亮态之间,有一条从亮态向暗态转移布居的单向两步通道,这个通道把原子布居转古巴大硕士学位论文wn4as aer ’ s7ffesls移到暗态,从而产生原子布居的相干捕获。 |
