Measurement of interaction-dressed Berry curvature and quantum metric in solids by optical absorption
The quantum geometric properties of a Bloch state in momentum space are usually described by the Berry curvature and quantum metric. In realistic gapped materials where interactions and disorder render the Bloch state not a viable starting point, we generalize these concepts by introducing dresse...
