量子光学弹簧

A Quantum Optical Spring

Amit Rai, G. S. Agarwal

摘要:

我们研究了量子光学弹簧的动力学,一种弹簧,其弹性常数根据另一个系统的量子态而经历离散的跳跃。我们证明了在量子动力学中存在着与腔QED中类似的动力学特征的回复和分数回复。在半经典极限下恢复了频率突变振子的结果。量子光学弹簧是可以想象的,例如,在严格量子的场的辐射压力的影响下,量子光学弹簧是可以想象的。我们的工作表明,如果驱动器被量子源取代,驱动系统通常会表现出非常不同的动力学。

英文摘要:

We study the dynamics of the quantum optical spring, i.e., a spring whose spring constant undergoes discreet jumps depending on the quantum state of another system. We show the existence of revivals and fractional revivals in the quantum dynamics reminiscent of similar dynamical features in cavity QED. We recover in the semi classical limit the results for an oscillator whose frequency undergoes a sudden change. The quantum optical spring is conceivable for example by a micromirror under the influence of radiation pressure by a field which is strictly quantum. Our work suggests that driven systems would in general exhibit a very different dynamics if the drive is replaced by a quantum source.
