AdS/CFT is a concrete framework where physics of a system can be formulated in ways that appear to have no overlap with each other. More precisely its a duality between a gauge theory in a “d” dimensional flat spacetime (called boundary theory) and a gravity theory (called the bulk theory) in a higher dimension that is asymptotically AdS. Establishing relations among various quantities on the bulk side and the boundary side is called building the dictionary. In this talk we discuss evidences of a new entry in the dictionary - the bulk Riemann curvature is related to boundary modular Berry curvature. The talk is based on arXiV: 1903.04493 by Bartlomiej Crech, Jan de Boer, Dongsheng Ge and Lampros Lamprou.
