Abstract: In this talk, I will briefly review the BCS-BES crossover in fermionic superfluidities. Starting from the idea initiated by Leggett, I will discuss quasi-particle and collective excitations in the unitarity regime, the correct way to achieve the critical temperature by Sa de Melo and NSR method, the topological phase transition in 2D, and the relation to the high-Tc superconductivity.
