Superconductivity and bosonic fluid emerging from moiré flat bands
Source abstract
Abstract
Here, the authors find a phenomenological theory of superconductivity in moir\'e flat band systems. With decreasing temperature, charge excitations are gapped, while charge excitations exist within the gap, shaping a bosonic fluid. Finite band width breaks the symmetry in these two-dimensional systems, making the bosonic fluid coherent and condense.
