Here, we develop a path integral treatment that provides a divergence-free description of the paired state in two-dimensional Fermi gases. Within this formalism, we derive the pseudogap temperature and the pair fluctuation spectral function, and compare these results with t","authors_text":"2), (2) Lyman Laboratory of Physics, Belgium, Harvard University, J.
