Camille Scalliet (email | web): I am a Research Fellow at the University of Cambridge where I hold a Hershel Smith Fellowship and Junior Research Fellowship at Sidney Sussex College. I am hosted by Prof. Michael E Cates in his 'Soft Matter theory' group. I moved there in late 2019 after obtaining my PhD in Theoretical Physics at the University of Montpellier, France. Before that, I did my undergraduate studies in Lyon, France, at the Ecole Normale Supérieure. During my PhD, I was interested in amorphous solids, such as emulsions, glasses, and jammed packings. By combining computational and theoretical approaches, I investigated the nature of glass formation, as well as the physical properties of amorphous materials. I was one of the first to investigate the physical consequences of a new phase of matter, discovered recently in a mean-field theory of glasses. I was awarded a L'Oréal-UNESCO Young Talents for Women in Science for my research and efforts to increase the visibility of women in science. These days, I am broadly interested in nonequilibrium statistical physics problems and active matter, in particular when disorder plays a role, as well as soft matter problems such as gelation.

Talk details: How does a deeply supercooled liquid flow close to the glass transition?
When a liquid is cooled rapidly enough to avoid crystallization, it becomes a supercooled liquid. The supercooled liquid is still in equilibrium, but becomes increasingly slow and viscous as temperature decreases. It eventually becomes so slow that it falls out of equilibrium and transforms into a glass at the glass transition temperature. While experiments can probe average, macroscopic quantities such as viscosity, little is know about how molecules/atoms move in a very viscous liquid. In this talk, I will describe how state-of-the-art computational methods allow us to reveal the microscopic motion in deeply supercooled liquids, and how this sheds new light on decades of experimental measurements and our more generally on our understanding of supercooled liquids.
