DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UKYhepth/45/
 ">Complexity and modular flows: Relating quantum information\, quantum fie
 ld theory and gravity</a>\nby Johanna Erdmenger as part of Theoretical Phy
 sics Seminars (Kentucky)\n\n\nAbstract\nI present recent work of our group
  on realizing computational complexity in conformal field theories in view
  of relating it holographically to complexity proposals in AdS gravity. Ga
 tes and cost functions in the CFT are introduced and used for a complexity
  definition based on geometric actions on Virasoro and Kac-Moody orbits. W
 e discuss a relation to the Euler-Arnold approach in Hamiltonian dynamics.
  In a complementary project\, we developed a new method for evaluating mod
 ular flows for 1+1-dimensional chiral fermions\, working directly from the
  resolvent in complex analysis. Both projects provide new ingredients for 
 exploring the connection between spacetime and entanglement.\n\nTalk based
