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 -function interacting Fermi gas, serves as a paradigm in quantum many-body physics, encompassing phenomena from spin-cha…

Low Energy Excitations of a 1D Fermi Gas with Attractive Interactions
Aashish Kafle, Ruwan Senaratne, Danyel Cavazos-Cavazos +5
The low-energy excitations of a two-component repulsive Fermi gas confined to one dimension are linear dispersing spin- and charge-density waves whose respective propagation veloci…
