Atomtronic Matter-Wave Optics
arXiv:2506.04735 · doi:10.1103/physrevlett.126.170402
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 , 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.
