Reviews of Modern Physics published an extended version of a talk by Prof. Bertrand Halperin, given at the March 2019 meeting of the American Physical Society, upon received the 2019 APS Medal for Exceptional Achievement in Research.
The article summarizes some of Prof. Halperin's work in areas linked to topological aspects of classical and quantum physics. Topics include quantum Hall effects, as well as the theory of melting in to dimensions and effects of vortex motion in a thin superconductor or a superfluid film.
