Dark-soliton-like excitations in the Yang–Gaudin gas of attractively interacting fermions

Yrast states are the lowest energy states at given non-zero momentum and provide a natural extension of the concept of dark solitons to strongly interacting one-dimensional quantum gases. Here we study the yrast states of the balanced spin- $\tfrac{1}{2}$ Fermi gas with attractive delta-function int...
