The BCS-BEC crossover is a research topic common to ultra-cold Fermi gases and the nuclear matter [1]. It represents a useful tool for testing fundamental theories such as the connection between superconductivity and fermionic superfluidity. At zero temperature, a reasonable description of this crossover can be obtained by a mean-field approach. In fact, this approximation provides accurate...
For fermions with two internal states and two-body interactions of large scattering length $a$, we express the number of nearby fermion triplets in terms of a quantity $C_3$ , the three-body contact.
We calculate the three-body contact in a high-temperature regime, similar to a virial expansion. First, at the unitary limit, we use a wave-function approach and we find an analytical formula...
