Eisenbud Lectures in Mathematics and Physics
20232024
Prof. Heckman received his A.B. from Princeton in 2004 and his PhD from Harvard in 2009. After postdocs at the IAS and Harvard, Heckman was a professor at UNC Chapel Hill. Since 2017 he has been a professor of physics at the University of Pennsylvania, where he holds a secondary appointment in math. Heckman's work involves a blend of techniques from physics and math centered on string theory and quantum field theory, which he uses to address questions in particle physics, cosmology, and quantum gravity, as well as topics in algebraic geometry, algebraic topology and information theory.

"Geometric Approach to Quantum Fields "
Abstract: Quantum field theory (QFT) is the universal language used by physicists to describe a wide variety of phenomena in Nature. Quite remarkably, this framework has also found many applications within pure mathematics. But what is quantum field theory and how is it characterized? In this talk, I highlight recent progress made in understanding QFT using the geometry of extra dimensions predicted by string theory. This includes the discovery of entirely new kinds of QFTs in a wide range of spacetime dimensions, leading to a remarkable interplay between physics and geometry.

"Top Down Approach to Global Categorical Symmetries"
Abstract: Symmetries play an important role in many areas of physics and mathematics. One recent discovery is that in quantum field theory (QFT), there are deep topological and categorical structures connected with global symmetries. Here we show how “top down” (i.e., stringy) constructions of QFTs provide a general template for constructing and studying these newfound structures. Using this perspective, we also extract the corresponding topological operators associated with such symmetries. This provides a systematic method for reading off further properties such as nontrivial fusion rules in the associated global symmetry category.

"Topological Approach to Symmetries in Quantum Gravity "
Abstract: One of the outstanding challenges in physics is to unify quantum theory with gravity. Based on various thought experiments, several pieces of lore have developed, including the statement that there are no global symmetries in quantum gravity. In this talk we discuss two applications of topology in addressing symmetries in quantum gravity. First, we use the top down approach to realizing global categorical symmetries to show how topological operators become dynamical once coupled to gravity. Second, we show how cobordism theory provides a novel tool in predicting specific physical objects in quantum gravity.
