Tomonaga-Luttinger liquid theory for one-dimensional attractive Fermi gases

Hai-Ying Cui, Yu-Hao Yeh, Randall G. Hulet +3

The one-dimensional (1D) Yang-Gaudin model-an integrable $\hat{I}´$-function interacting Fermi gas, serves as a paradigm in quantum many-body physics, encompassing phenomena from spin-ch…
