Matterwave interferometry with Bose Einstein Condensates (BEC) promises exciting prospects in inertial sensing and research on fundamental physics both on ground and in space. BECs can be efficiently created using atom chips and compact setups have already been shown. However, for transportable or space applications further reduction in complexity is desired in order to lower size, weight, and power demands.
I will present a nano-structured atom chip with results on magneto-optical trapping and sub-Doppler cooling using only a single beam of light. This reduces the overall complexity and promises greater long-term stability. We demonstrate state-of-the-art performance and magnetic trapping with the atom chip.
