Reminder: Special CM Theory Seminars: Today @ 12:00pm

[Gardner, Joanna D.]

Good Morning,

The Ho Group is hosting special seminar speaker Dr. Pengfei Zhang, Institute for Advance Study, Tsinghua University. Please see below for his seminar information. We hope to see you there today!


=================================

Time :  Friday,  April 7, 12:00pm-1:00pm. Location :  PRB, Room 1080

Speaker :  Pengfei Zhang,   Institute for Advance Study,  Tsinghua University 

Title : Sachdev-Ye-Kitaev model and its generalization with tunable Lyapunov exponent

Abstract :   In this talk I will first give an introduction to the SYK model which is a solvable model in large N limit. I will mainly focus on the four point function and its effective action. After this I'd like to talk about our recent work in which we couple a small SYK model to a larger SYK bath. This leads to a model with tunable Lyapunov exponent. We also generalize it to higher dimension where we can study the butterfly effect and related inequality derived by using Holographic duality.

Sincerely,
Joanna Gardner
