Title: Aspects of symmetry and gravity, Abstract:  I will review the core questions in quantum field theory and gravity for the research in my group.  I will also describe recent developments in the study of symmetry of quantum systems and their potential implications for gravity. 

Abstract:  I will review the core questions in quantum field theory and gravity for the research in my group.  I will also describe recent developments in the study of symmetry of quantum systems and their potential implications for gravity.  We are starting a new seminar series with the working title Broad Theory Seminar. Its goal is […]

Title: Topological defects in liquid crystals, Abstract: I will present an introduction to the theory of topological defects in materials, giving an intuitive overview of homotopy theory and exploring how it is used to understand physically (and often visually!) observable quasiparticles. I will focus primarily on nematic liquid crystals, while highlighting analogous phenomena in other […]
