The main focus of the talk is to study a system of ultracold Fermi gas
from the BCS to the unitary regime, using low-momentum effective
interaction. The goal will be to calculate the equation of state using
the Bogoliubov many-body perturbation theory.
In particular I will discuss the Bertch parameter in the unitary regime and its dependence on
the renormalization scale.
