Mathematical Physics Seminar, Mondays

Beginning immediately, until at least December 31, all seminars will take place virtually, through Zoom.

The seminar on mathematical physics will be held on Mondays from 10:30 – 11:30am ET. Please email the seminar organizers to learn how toattend. This year’s Seminar will be organized by Yoosik Kim (, Tsung-Ju Lee (, and Yang Zhou (

The list of speakers for the upcoming academic year will be posted below and updated as details are confirmed. Titles and abstracts for the talks will be added as they are received. 

9/14/2020Lino Amorim (Kansas State University)Title: Non-commutative Gromov-Witten invariants

Abstract:  I will describe an analogue of Saito’s theory of primitive forms for Calabi-Yau A-infinity categories. Under some conditions on the Hochschild cohomology of the category, this construction recovers the (genus zero) Gromov-Witten invariants of a symplectic manifold from its Fukaya category. This includes many compact toric manifolds, in particular projective spaces.
9/21/2020Yuhan Sun (Rutgers)Title: Displacement energy of Lagrangian 3-spheres

Abstract:  We study local and global Hamiltonian dynamical behaviors of some Lagrangian submanifolds near a Lagrangian sphere S in a symplectic manifold X. When dim S = 2, we show that there is a one-parameter family of Lagrangian tori near S, which are nondisplaceable in X. When dim S = 3, we obtain a new estimate of the displacement energy of S, by estimating the displacement energy of a one-parameter family of Lagrangian tori near S.
9/28/2020Shota Komatsu (CERN)Title: Wilson loops as matrix product states

Abstract:  In this talk, I will discuss a reformulation of the Wilson loop in large N gauge theories in terms of matrix product states. The construction is motivated by the analysis of supersymmetric Wilson loops in the maximally super Yang–Mills theory in four dimensions, but can be applied to any other large N gauge theories and matrix models, although less effective. For the maximally super Yang–Mills theory, one can further perform the computation exactly as a function of ‘t Hooft coupling by combining our formulation with the relation to integrable spin chains.
