GQFI-WST Seminar: Mario Flory "Geometry of Complexity in CFT2"

In this talk, Mario Flory (Jagiellonian University) studies circuit and state complexity in the universal setting of (1+1)-dimensional conformal field theory and unitary transformations generated by the stress-energy tensor. He provides a unifi​ed view of assigning a cost to circuits based on the Fubini-Study metric, iteratively solves the emerging integro-diff​erential equation for sample optimal circuits and discusses the sectional curvature of the underlying geometry. He also discusses the relation of his work to Euler-Arnold type equations such as the Korteweg-de Vries and Hunter-Saxton equations. The Virtual Seminar Series “GQFI-Warsaw String Theory” (GQFI-WST) is a joint initiative between the strings/holography groups at the Albert Einstein Institute (AEI) in Potsdam and the University Warsaw.
