Collège de France Young Researchers Webinar

february 12, 2021

Young researchers at the Collège de France, grouped together in the ChADoC association (Chercheurs Associés et Doctorants du Collège de France) invite you to attend a series of monthly webinars presenting the research work of doctoral students, post-docs, ATERs and lecturers at the Collège de France in short presentations lasting around twenty minutes, accessible to all.

These presentations provide an insight into research "in the making" in a variety of fields, from experimental sciences to the humanities, and aim to show the richness and diversity of the work being pursued by new generations of scientists and researchers.

The next session, entitled "Exploring matter with quantum gases", will be presented by Brice Bakkali-Hassani, a doctoral student at the Kastler-Brossel laboratory, and will take place online on Wednesday February 24 at 6 p.m. via the following link (advance registration required): https: //us02web.zoom.us/webinar/register/WN_EfvwjjXYRBWiaCgWCYgXaQ

Exploring matter with quantum gases

In 1937, the Soviet physicist Pyotr Kapitsa, who went on to win the 1978 Nobel Prize, discovered an astonishing property of helium: its superfluidity!

When cooled to very low temperatures, this substance remains in a liquid state and can flow through channels without the slightest viscosity. This property, uncommon among ordinary fluids, is one of the behaviors explored with quantum gases.

In this webinar, Brice Bakkali-Hassani will show you how to make and manipulate quantum gases. He'll show you how to trap and cool assemblies of atoms using laser beams. Then he'll explain the curious phenomena that such an experiment enables us to observe... and which form the subject of his research.
