Dominant Excitonic Superconductivity in a Three-component Hubbard Chain
Sheng Chen, Qiao Yang, Wéi Wú +1
Understanding superconductivity emerging from repulsive fermions remains a major challenge in condensed matter physics. In this paper, we investigate the pairing tendencies in a on…

Nonperturbative quantum field theory for pseudo-Goldstone modes, slow-Goldstone modes, and their quantum chaos
Fadi Sun, Jinwu Ye
In this work, we develop a novel form of non-perturbative theory to identify a light pseudo-Goldstone mode with a small mass, as well as a new type of Goldstone mode with a tiny sl…
