Hydrodynamics of the one-dimensional Bose gas : atom losses (Jerôme Dubail / LPT / Seminar). – 14/12, 14H.

14 December 2021; 14h00 - 16h00

Jerôme Dubail (LPCT, Nancy)

I will briefly introduce “Generalized Hydrodynamics”, the hydrodynamic description of one-dimensional integrable systems [1,2], and review the experimental results [3,4] obtained by the groups of I. Bouchoule in Palaiseau and D. Weiss in Penn State. One important experimental effect not taken into account in GHD is the atom losses : I will discuss perspectives on how to include these [5,6,7].
