Luther-Emery liquid and dominant singlet superconductivity in the two-orbital Hubbard chain

P Laurell, J Herbrych, G Alvarez, E Dagotto - arxiv preprint arxiv …, 2023 - arxiv.org
We investigate the pairing tendencies in the two-orbital Hubbard chain at intermediate
repulsive interaction strengths $ U $, and for degenerate orbitals. At half-filling and large $ U …
