冷费米气体中的量子随机行为:声子传播

Quantum stochastic behaviour in cold Fermi gases: Phonon propagation

En-Tsung Hsiang, Da-Shin Lee, Chi-Yong Lin, Ray J. Rivers

摘要:

研究了可调谐冷费米气体中量子涨落对声子传播的影响。我们表明,这些波动可以被解释为诱导一个随机的(声学)时空。由这种随机行为引起的飞行时间的变化在BEC和BCS制度之间的过渡区域中可能是显着的。

英文摘要:

We examine the effect of quantum fluctuations in a tunable cold Fermi gas on the propagation of phonons. We show that these fluctuations can be interpreted as inducing a stochastic (acoustic) space-time. The variation in times of flight induced by this stochastic behaviour can be significant in the transition region between BEC and BCS regimes.
