PCTS Seminar Series: Deep Learning for Physics

Autoregressive Simulation of Many-Body Quantum Systems
Or Sharir
2:00pm|*Princeton University, 407 Jadwin Hall, PCTS Seminar Room*

Understanding phenomena in systems of many interacting quantum particles, known as quantum many-body systems, is one of the most sought-after objectives in contemporary physics research. The challenge of simulating such systems lies in the extensive...

PCTS Seminar Series: Deep Learning for Physics

Machine Learning Techniques for Many-Body Quantum Systems
Giuseppe Carleo
11:45am|*Princeton University, 407 Jadwin Hall, PCTS Seminar Room*

In this introductory seminar I will cover the main machine learning techniques so-far adopted to study interacting quantum systems. I will first introduce the concept of neural-network quantum states [1], a representation of the many-body wave...

Computer Science/Discrete Mathematics Seminar I

Towards a theory of non-commutative optimization: geodesic 1st and 2nd order methods for moment maps and polytopes
Rafael Oliveira
10:30am|Simonyi Hall 101

Scaling problems, such as operator scaling and tensor scaling, have recently found several applications in diverse areas of math and CS. They have been used to give efficient algorithms for non-commutative rational identity testing, compute the...

Analysis Seminar

Strong ill-posedness of the logarithmically regularized 2D Euler equations in the borderline Sobolev space
5:00pm|Simonyi Hall 101

The well-posedness of the incompressible Euler equations in borderline spaces has attracted much attention in recent years. To understand the behavior of solutions in these spaces, the logarithmically regularized Euler equations were introduced. In...

Symplectic Dynamics/Geometry Seminar

Koszul duality and Knot Floer homology
Thomas Hockenhull
3:30pm|*Princeton University, Fine Hall 224*

‘Koszul duality’ is a phenomenon which algebraists are fond of, and has previously been studied in the context of '(bordered) Heegaard Floer homology' by Lipshitz, Ozsváth and Thurston. In this talk, I shall discuss an occurrence of Koszul duality...

Members’ Seminar

Length and volume in symplectic geometry
Daniel Cristofaro-Gardiner
2:00pm|Simonyi Hall 101

Symplectic capacities are measurements of symplectic size. They are often defined as the lengths of certain periodic trajectories of dynamical systems, and so they connect symplectic embedding problems with dynamics. I will explain joint work...

Computer Science/Discrete Mathematics Seminar I

Learning arithmetic circuits in the average case via lower bounds
Ankit Garg
11:00am|Simonyi Hall 101

The problem of learning arithmetic circuits is the following: given a polynomial as a black box that is promised to have a small arithmetic circuit computing it, can we find this arithmetic circuit? This problem is hard in the worst case and so...
