Abstract:

In this introductory seminar, I will briefly explain the mean-field spin glass, especially focusing on the classical Sherrington-Kirkpatrick (SK) model. I will explain its nontrivial low temperature thermodynamics and Parisi's replica symmetry breaking solution. Then I will discuss its quantum version, which has a close relation with the SYK model in the double-scale limit. The SYK model is a very promising holographic quantum mechanical model that is dual to AdS_2 JT gravity. Due to its relatively simple (but not too simple) struture, there are many proposals to simulate SYK model in a quantum platform. On the other hand, since SYK model has a connection to spin glass, we can start with simulating the latter and improve the techniques to simulate the SYK model, which may be helpful for understanding quantum gravity.
