Lauriane’s Short Profile

laurianebw
Lauriane Chomaz was born on the 19
th November 1986 in Orsay (France). In 2010 she graduated with an M.Sc. from l’Ecole Polytechnique (Palaiseau, France). She then undertook doctoral studies under the supervision of Prof. Jean Dalibard and investigated, on a cold Rubidium 87 experiment, the thermodynamics and the superfluidity of Bose gases constrained to bidimensionality (2D). She obtained her Ph.D in November 2014 from l’Ecole Normale Supérieure (Paris, France). During her PhD, she and her team observed for the first time the superfluid behavior of a 2D Bose gas and pioneered the investigation of the transverse condensation phenomenon occurring in uniform 2D Bose gases. They were also interested in the dynamics, in particular the nucleation of topological defects called vortices, when quenching across this transition and they highlighted its compliance with Kibble–Zurek mechanism. After six month as an associate researcher at Collège de France in which she extended her doctoral work by participating to the construction of the next generation of the experiment, she joined in April 2015 the group of Univ. Prof. Francesca Ferlaino as a post-doctoral fellow on the cold Erbium machine. She and her team are now concentrating on different aspects of the physics of gases with dipolar interactions.
