A fluid of 10 ultracold fermions — •Lars Helge Heyen1, Giuliano Giacalone1, and Stefan Floerchinger21Universtität Heidelberg, Deutschland — 2Friedrich-Schiller-Universität Jena, Deutschland

Recent experiments in heavy-ion collisions have challenged our understanding of the applicability of fluid dynamics by showing typical signatures of collective flow with only a small number of final state particles. Motivated by this, we investigate fluidlike behavior in a system of few ultracold fermions. Our key observable is the inversion of the shape of the cloud after release from an anisotropic harmonic trap. This elliptic flow is shown to persist down to as low as 10 particles. I discuss ongoing efforts to understand these experimental observations.
