• Abstract: Matterwaves made up of ultra-cold quantum-degenerate atoms have enabled the creation of tools having unprecedented sensitivity and precision in measuring gravity, rotation or magnetic fields. Applications range from gravitational wave detection and tests of Einstein's equivalence principle to inertial sensing for navigation and gravitational gradient sensing for oil and mineral exploration. In this letter, we introduce atom-optics as a novel tool of manipulating matterwaves in ring-shaped coherent waveguides. We collimate and focus matterwaves derived from Bose-Einstein Condensates (BECs) and ultra-cold thermal atoms in ring-shaped time-averaged adiabatic potentials. We demonstrate `delta-kick cooling' of BECs, reducing their expansion energies by a factor of 34. The atomtronic waveguide ring has a radius of only $485\,\mu m$, compared to other state-of-the-art experiments requiring zero gravity or chambers of ten meter. This level of control with extremely reduced spatial requirements is an important step towards atomtronic quantum sensors.

  We develop an atomic sensor that employs a $p$-orbital Bose-Einstein condensate in an optical lattice to project gravitational wave signals into an orbital squeezed state. This entangled state couples linearly to the spacetime distortion signals received via a Michelson interferometer. Results suggest that atomic orbital squeezing offers a compelling alternative to conventional techniques.

  NASA's Cold Atom Lab operates onboard the International Space Station as a multi-user facility for studies of ultracold atoms. Atom interferometers are a class of quantum sensors which can use freely falling gases of atoms cooled to sub-photon-recoil temperatures. A three-pulse Mach-Zehnder interferometer was studied to understand limitations from the influence of ISS vibrations. Ramsey shear-wave interferometry was used to manifest interference patterns in a single run that were observable for over 150 ms free-expansion time.
