Currently, there is great interest in devising experimental protocols for directly probing the Berry curvature, quantum metric, and orbital moment of Bloch electrons. [*] Central to this effort is the notion that ground-state quantum geometry can be related to the excitation spectrum via optical sum rules. In this talk I will review those ideas, from their early inception to recent developments.<\/p>\n<p><strong>[*] <\/strong>Image emprunt\u00e9e \u00e0 S.
