Abstract
The main advantage of the Krylov basis approach to quantum complexity is its reliance on only two physical inputs: the evolving Hamiltonian and the initial state. In this talk, I will discuss how these measures of complexity depend on and exhibit universal behaviour under infinitesimal variations of these ingredients. I will also introduce several novel tools for quantifying these variations within the Krylov framework. The talk will be based on an upcoming papers with Vijay Balasubramanian and Joan Simon.
Speaker
Prof. Pawel Caputa is at the Department of Physics, Stockholm University, in Sweden. He received his Ph.D. from the Niels Bohr Institute, Copenhagen, in Denmark. Together with Tadashi Takayanagi, he has been working on constraints on holographic field theories from entanglement dynamics. He has been developing quantum information tools, such as measures of complexity and entanglement, in quantum field theories and using them to understand the relation between spacetime geometry and information. His works also encompass various aspects of integrability, 1/N corrections, and representation theory in gauge theories. He is also a member of the “It from Qubit” international collaboration from Simons Foundation, on “Quantum Fields, Gravity and Information”.
The seminar will be broadcasted online by Zoom.
Interested people are free to join, without registration in advance.
