Bowen Yang '18 was the recipient in 2018 of the Rufus B. Kellogg University Fellowship, one of the Amherst College Fellowships for graduate study. The Kellogg is awarded for three years of study to a recent graduate "best equipped for study and research." The recipient is asked to return to campus in the third year of the fellowship to give a lecture or presentation.

Bowen is currently a graduate student in mathematical physics at Caltech. He seeks to classify topological quantum systems using mathematical tools such as topology and operator algebras.

"In this talk, we will explore two very different worlds: the world of quantum spin systems and the world of coarse geometry. Quantum spin systems are powerful mathematical models of interacting quantum many-body systems. They are widely studied in condensed matter physics, mathematical physics as well as quantum information theory. On the other hand, since its introduction by John Roe, coarse geometry has remained a beautiful and effective description of large-scale behavior of spaces. After introducing both worlds separately, I will explain an ongoing effort to connect the two through an idea called homology. I will only assume backgrounds in calculus and linear algebra."

This event is sponsored by the Office of Fellowships and the Department of Mathematics and Statistics.
