The Energy-Based Learning Model

MATHEMATICAL PICTURE LANGUAGE

May 18, 2021      10:00 am
Speaker: Yann LeCun - New York University and Facebook

One of the hottest sub-topics of machine learning in recent times has been Self-Supervised Learning (SSL). In SSL, a learning machine captures the dependencies between input variables, some of which...

Lieb-Thirring bounds and other inequalities for orthonormal functions

MATHEMATICAL PICTURE LANGUAGE

May 4, 2021      10:00 am
Speaker: Rupert Frank - Ludwig-Maximilians-Universität Münchens

Lieb-Thirring inequalities are a mathematical expression of the uncertainty and exclusion principles in quantum mechanics. They were introduced by Lieb and Thirring in 1975 in their proof of stability of...

Dimerization in quantum spin chains with O(n) symmetry

MATHEMATICAL PICTURE LANGUAGE

April 27, 2021      10:00 am
Speaker: Bruno Nachtergaele - University of California Davis

We consider spin-S quantum spin chains with a family of O(2S+1)-invariant nearest-neighbor interactions and discuss the ground state phase diagram of this family of models. Using a graphical representation for...

Emerging frontiers in nuclear magnetic resonance

MATHEMATICAL PICTURE LANGUAGE

April 20, 2021      10:00 am
Speaker: Haribabu Arthanari - Harvard Medical School

Nuclear Magnetic Resonance (NMR) is a powerful spectroscopic technique that provides information about matter at an atomic resolution. One of the applications of NMR is to decipher the molecular architecture of biomolecules including nucleic...

Aspects of M Theory

MATHEMATICAL PICTURE LANGUAGE

April 13, 2021      10:00 am
Speaker: Jens Hoppe - Technische Universitat Braunschweig

After giving a brief introduction to Membrane Theory and its matrix regularization, commenting on an inherent dynamical symmetry for all M-branes (the related “reconstruction-algebra” for M=1, strings, being the Virasoro algebra),...

The wondrous world of hyperfinite subfactors

MATHEMATICAL PICTURE LANGUAGE

March 30, 2021      10:00 am
Speaker: Dietmar Bisch - Vanderbilt University

The hyperfinite II1 factor contains a wealth of subfactors, many of which give rise to new and fascinating mathematical structures. For instance, the standard representation of a subfactor generates a...

Noncommutative real algebraic geometry and quantum games

MATHEMATICAL PICTURE LANGUAGE

March 23, 2021      10:00 am
Speaker: William Helton - University of California San Diego

The last two decades produced a substantial noncommutative (in the free algebra) real and complex algebraic geometry. The aim of this subject is to develop a systematic theory of equations...

Exploring new scientific frontiers with programmable quantum systems

MATHEMATICAL PICTURE LANGUAGE

March 16, 2021      10:00 am
Speaker: Mikhail Lukin - Harvard University

I will discuss recent developments at a new scientific interface between quantum optics, quantum many-body physics, information science and engineering. Specifically, I will focus on two examples at this interface...
