拉比振荡与宏观量子叠加态

Rabi oscillations and macroscopic quantum superposition states

Marco Frasca

摘要:

在强耦合条件下,考虑了二能级原子与单模辐射场的相互作用。结果表明,与最近关于约瑟夫森结中拉比振荡的结果一致(Y。中村优A. Pashkin和J.S. Tsai,Phys. Rev. Lett. { \bf 87},246601(2001)),Rabi频率在大量光子的极限下确实与第一类整数阶Bessel函数成比例,并且修饰态是宏观量子叠加态。为了解决这个问题,分析使用的是由双戴森级数和双波近似。

英文摘要:

A two-level atom interacting with a single radiation mode is considered, without the rotating-wave approximation, in the strong coupling regime. It is shown that, in agreement with the recent results on Rabi oscillations in a Josephson junction (Y. Nakamura, Yu. A. Pashkin and J. S. Tsai, Phys. Rev. Lett. {\bf 87}, 246601 (2001)), the Rabi frequency is indeed proportional to first kind integer order Bessel functions in the limit of a large number of photons and the dressed states are macroscopic quantum superposition states. To approach this problem analytically use is made of the dual Dyson series and the rotating-wave approximation.
