YMSC Probability Seminar | Spectral gap and two point functions for spin glass models

Time：2023-12-21, Thursday, 16:00-17:00

Venue：C548, Shuangqing Complex Building

Organizer：吴昊，杨帆，姜建平，顾陈琳

Speaker：Changji Xu Harvard University

Abstract：

In this talk, I will discuss recent progress in mean-field spin glass models. Specifically, I will present a method to prove that the spectral gap of the Dirichlet form associated with Glauber dynamics is of order one at sufficiently high temperatures. Furthermore, I will talk about estimates on two-point functions for the SK model under high-temperature conditions.

Harvard University

I am a postdoctoral fellow in the Center of Mathematical Sciences and Applications at Harvard University. My mentor is Prof. Horng-Tzer Yau. I received my Ph.D. in statistics at the University of Chicago in 2020, advised by Prof. Jian Ding, and a B.S. in mathematics at Tsinghua University in 2015.

I am interested in probability theory.

Extreme gap problems for random matrices
AbstractIn the talk, I will give a brief review of known results on the extreme gap problems (smallest and largest gaps of the eigenvalues) of various random matrix ensembles. Then I will present our recent work about the smallest gap of the Gaussian symplectic ensemble. This completes the picture of the small gap problem of classical Gaussian β ensembles for β=1, 2, 4. Our analysis can poten...

Algebraicity of Higher Green Functions at a CM Point
AbstractBy the classical theory of complex multiplication, the modular j-function takes algebraic values at CM points. It is an interesting question to ask about the algebraic nature of other types of automorphic functions at CM points. For the automorphic Green function at integral parameters, Gross and Zagier conjectured in the 1980s that their values at a CM point is essentially the logarith...
