High Resolution Imaging and Control of Quantum Degenerate $^{133}$Cs-$^6$Li Bose-Fermi Mixtures

POSTER

Abstract

We present progress on the investigation of Bose-Einstein condensates of $^{133}$Cs atoms immersed in degenerate Fermi gases of $^{6}$Li atoms. Deep in quantum degeneracy, fermion excitations near the Fermi surface can induce effective interactions between condensed bosons. The strength and sign of this mediated interaction is predicted to oscillate at a length scale given by the Fermi wavelength, which is about 1$\mu$m in our system. We develop a high resolution microscope and a digital micro-mirror device to image and manipulate the degenerate quantum mixtures at a length scale close to the Fermi wavelength. The upgraded system permits new schemes to characterize the long range nature of the fermion-mediated interactions between bosons, and offers a versatile platform to study novel quantum phases and dynamics of interacting Bose-Fermi mixtures.
