挤压池中二能级系统的Zeno和Anti Zeno效应

Zeno and Anti Zeno effect for a two level system in a squeezed bath

D. F. Mundarain, J. Stephany

摘要:

本文讨论了指数衰减系统中Zeno(QZE)或anti-Zeno(QAE)效应的出现。本文研究了一个连续受监控的二能级系统与压缩池相互作用的量子动力学。我们发现,系统的行为严重依赖于挤压浴的制备方式。对于特定的选择的压缩相位的系统显示芝诺或反芝诺效应的条件下,它会指数衰减,如果没有进行测量。这个结果允许一个明确的解释,在等效自旋系统与虚构的磁场相互作用。

英文摘要:

We discuss the appearance of Zeno (QZE) or anti-Zeno (QAE) effect in an exponentially decaying system. We consider the quantum dynamics of a continuously monitored two level system interacting with a squeezed bath. We find that the behavior of the system depends critically on the way in which the squeezed bath is prepared. For specific choices of the squeezing phase the system shows Zeno or anti-Zeno effect in conditions for which it would decay exponentially if no measurements were done. This result allows for a clear interpretation in terms of the equivalent spin system interacting with a fictitious magnetic field.
