Polariton-induced unconventional superconductivity and emergent SU(2) symmetry in moiré flat bands

Abstract

We propose a polariton-moiré coupled system to realize an exact solvable model of strongly correlated superconductors. The polariton condensate induces intervalley attraction between moiré electrons in quasi-flat topological bands, leading to emergent SU(2) symmetry and exactly solutions of the many-body ground state. This system expands the condensate-induced superconductivity to the strong-correlation regime, enabling superconductivity at elevated temperatures and allowing the study of non-Fermi liquid states with a solvable, predictive model. It is promising as a versatile platform for emulating unconventional superconductivity and other strongly correlated phenomena in complex, correlated materials.
