Although quantum degenerate gases of neutral atoms have shown remarkableprogress in the study of many body quantum physics, condensed matter physics,precision measurements, and quantum information processing, experimentalprogress is needed in order to reach their full potential in these fields. Morecomplex spatial geometries as well as novel methods for engineering interestinginteractions are needed. Here we demonstrate a novel experimental platform forthe realization of quantum degenerate gases with a wide range of tune-abilityin the spatial geometries experienced by the atoms and with the possibility ofnon-trivial long-range interactions both within and between multiple 87RbBose-Einstein condensates (BECs). We explore the use of a large mode-volumebow-tie ring cavity resonant at two wavelengths, $\lambda$ =1560 and 780 nm,for the creation of multiple BECs within a Malleable optical trap which alsopossesses the ability of photon-mediated long-range interactions. By excitingdiverse transverse modes at 1560 nm, we can realize many optical trappinggeometries which can open the door to spatial quantum state engineering withcavity-coupled BECs. As representative examples we realize a BEC in thefundamental TEM00 and a double BEC in the TEM01 mode of the cavity. Bycontrolling the power between the fundamental and the higher transverse cavitymode, splitting and merging of cold thermal atomic ensemble is shown as well asthe potential of creating more complex trapping geometries such as uniformpotentials. Due to the double resonance of the cavity, we can envision aquantum network of BECs coupled via cavity-mediated interactions in non-trivialgeometries.
