Excitonic-Superconducting Coexistence and Emergent Nematic Superconductivity Driven by Spontaneous Symmetry Breaking
feeds.aps.org · By Fei Yang, Ruigang Li, Junwei Liu & Binghai Yan ·
The Brief
- Excitonic insulating and superconducting orders are generally regarded as mutually exclusive electronic instabilities.
- The paper reports a self-consistent microscopic theory of electronic systems hosting an excitonic insulating phase.
- The theory finds excitonic-superconducting coexistence and emergent nematic superconductivity driven by spontaneous symmetry breaking.
Why it matters
The work challenges the assumption that excitonic insulating and superconducting order cannot coexist, which could guide the search for correlated electron phases with nematic superconductivity.
