Query: Onset of a Pseudogap Regime in Ultracold Fermi Gases   We show, using an ab initio approach based on Quantum Monte Carlo technique,
that the pseudogap regime emerges in ultracold Fermi gases close to the unitary
point. We locate the onset of this regime at a value of the interaction
strength corresponding to (k_{F}a)^{-1}\approx -0.05 (a - scattering length).
We determine the evolution of the gap as a function of temperature and
interaction strength in the Fermi gas around the unitary limit and show that
our results exhibit a remarkable agreement with the recent wave-vector resolved
radio frequency spectroscopy data. Our results indicate that a finite
temperature structure of the Fermi gas around unitarity is more complicated and
involves the presence of the phase with preformed Cooper pairs, which however
do not contribute to the long range order.
