Original · EN

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.
