R. G. Herb Condensed Matter Seminar
Out-of -time-order correlators in solid state physics
Date: Tuesday, April 12th
Time: 10:00 am
Place: 5280 Chamberlin Hall
Speaker: Lara Faoro, CNRS
Abstract: Out-of-time-order correlators, introduced recently in the context of quantum gravity describe the delocalization of information in quantum systems. <br>
In classical chaotic systems, these correlators are known to grow exponentially with the Lyupanov exponent. I discuss the behavior of these correlators in canonical examples of solid state quantum chaotic systems: disordered electrons with and without phonon interaction. In conclusion, I discuss possible measurements of these correlators in superconducting systems.
Host: Robert Mcdermott
