Oscillations of a Bose-Fermi mixture

ORAL

Abstract

Mixtures of quantum fluids lie at the forefront of research into strongly-correlated quantum matter. In our dual-species ultracold atomic gas experiment, we study the dynamics of impurities interacting with a BEC bath. In equilibrium, impurities can form well-defined quasiparticles, Bose polarons, by interacting with the BEC [1]. We study their dynamics by inducing center-of-mass oscillations in both species at varying impurity-bath interaction strength. Our observations offer a promising starting point in the experimental study of the dynamics of Bose-Fermi mixtures in the impurity limit.
