BEC-Cryostat Interface: A Novel Platform for Hybrid Quantum Systems*

We present our experimental progress towards the implementation of a unique BEC-cryostat interface. This apparatus allows for the control and manipulation of ultracold atoms in close proximity to cryogenic surfaces. Such a system enables us to realize a hybrid quantum system consisting of a BEC strongly coupled magnetically to an ultra-high Q mechanical resonator, thus enabling precise atomic sensing of mechanical motion [1]. Furthermore, the unprecedented sensitivities afforded by our atomic system open avenues to surface studies of correlated electronic systems at cryogenic temperatures.\\[4pt] [1] S. K.
