In situ imaging and manipulation of Cs-Li Bose-Fermi mixture
POSTER
Abstract
Quantum degenerate mixtures of bosonic and fermionic atoms are a powerful platform for quantum simulation, as well as rich physical systems in their own right. This poster reports on our investigation of cesium Bose-Einstein condensate immersed in a lithium degenerate Fermi gas. Based on in situ imaging and optical potential projection, we observe intriguing sound propagation dynamics in the mixture across an interspecies Feshbach resonance. Surprisingly, the sound mode persists across the resonance. Imaging the two species in each mixture, we investigate the beyond-mean-field correlations of bosons and fermions induced by interspecies interactions.
