Correlation-driven enhancement of pairing in a nematic Hund's metal
The study investigates how Hund's correlations affect superconductivity in a multiorbital nematic metal. It finds that dynamical correlation effects beyond simple quasiparticle descriptions are crucial for superconductivity to remain robust in the Hund regime. These correlations simultaneously enhance orbital gap differentiation and prevent coherence collapse, suggesting pairing mechanisms with different energy scales lead to distinct superconducting properties.
