Hamilton Colloquium Series, Roland Bauerschmidt, University of Cambridge"Different Perspectives in Statistical Physics" Jadwin A-10
Thu, Dec 1, 2022, 4:00 pm5:00 pm

The use of different perspectives on a problem is a very powerful principle in statistical physics, and has been especially important in mathematical physics. I will illustrate this theme with old and recent applications. These include the interpretation of QFTs at imaginary time as statistical fields, the relation of statistical fields to…

A free lecture open to the public.
Mathematical Physics Seminar, Tues, Nov. 15, 4:30pm, Jadwin A06, Eliran Subag, Weizmann Institute, "Free Energy Landscapes and a Generalized TAP Approach"

In the Thouless-Anderson-Palmer approach to mean-field spin glasses, the free energy is presented as the infimum of a functional which TAP defined over the space of all possible magnetization vectors, subject to a convergence condition. Its self-averaging over exponentially many solutions at low temperature seems to be taken for granted, though…

Although lattice Yang-Mills theory is easy to rigorously define, the construction of a satisfactory continuum theory is a major open problem in dimension d ≥ 3. Such a theory should assign a Wilson loop expectation to each suitable collection L of loops in d-dimensional space. One classical approach is to try to represent this expectation as a…

Mathematical Physics Seminar, Tues Mar 29, 4:30PM, Jadwin A06, Vieri Mastropietro, IAS and University of Milan, "Anomaly non-renormalization on a lattice"
Tue, Mar 29, 2022, 4:30 pm4:30 pm

The Adler-Bardeen non-renormalization is a basic property of anomalies with important physical implications, ranging from particle physics to condensed matter. We prove its validity in lattice models at a non-perturbative level, focusing in particular on fermion-vector boson models in 3+1 and 1+1 dimensions. The proof relies on regularity…

Mathematical Physics Seminar, Tues Mar 22, 4:30pm, Jadwin A06, Louis-Pierre Arguin, Baruch College & Graduate Center CUNY``Statistical mechanics perspective on the large values of the Riemann zeta function’’
Tue, Mar 22, 2022, 4:30 pm4:30 pm

I will give an account of the recent progress in probability and in number theory to understand the large values of the zeta function on the critical line, especially in short intervals. The problems have interesting connections to statistical mechanics of disordered systems, both in their interpretations…

Mathematical Physics Seminar, Tues Mar 15, 4:30pm, Jadwin A06, Amol Aggarwal, IAS, Princeton,"Six-Vertex Model and the KPZ Universality Class "
Tue, Mar 15, 2022, 4:30 pm4:30 pm

In this talk we explain recent results relating the six-vertex model and the Kardar-Parisi-Zhang (KPZ) universality class. In particular, we describe how the six-vertex model can be used to analyze stochastic interacting particle systems, such as asymmetric exclusion processes, and how infinite-volume pure…
