Abstract
I demonstrate how platforms based on optically and magnetically levitated test masses enable both the discovery of new physics and the development of new applied technologies.
In particular I'll review the scientific motivation, design and recent construction of node 1 of the high frequency gravitational wave detector at Northwestern University (The levitated sensor detector - LSD), discuss the near term engineering data run of the instrument and the medium term prospects the instrument holds for placing bounds on the QCD axion from the detection or nondetection of HFGW's. I will delineate how adding additional detection nodes around the globe expands the instrument's science case.
Furthermore I'll focus on the role that levitated systems play in the development of new industrially relevant technologies. Ranging from highly applied systems such as inertial navigation systems and gravimeters to more novel technology such as laboratory benchmarks for deep space nuclear propulsion.
