Evolution of Cooper pairs with zero-center-of-mass momentum and their first-order correlation function in a two-dimensional ultracold Fermi gas near the observed Berezinskii-Kosterlitz-Thouless transition

Morio Matsumoto, Daisuke Inotani, Yoji Ohashi

We investigate the center-of-mass momentum distribution $n_{\mathbf{Q}}$ of Cooper pairs and their first-order correlation function $g_1(r)$ in a strongly interacting two-dimens…
