Atom interferometers allow determining inertial effects to high accuracy. Quantum-projection noise as well systematic impose demands on large atomic flux ultra-low expansion rates. Here we report a high-flux source of ultra-cold atoms with free rates near the Heisenberg limit directly upon release from trap. Our results are achieved in time-averaged optical dipole trap and enabled through dynamic tuning scattering length across two orders magnitude interaction strength via magnetic Feshbach...
The capability to reach ultracold atomic temperatures in compact instruments has recently been extended into space. Ultracold amplify quantum effects, while free-fall allows further cooling and longer interactions time with gravity - the final force without a description. On Earth, these devices have produced macroscopic phenomena such as Bose-Einstein condensation (BECs), superfluidity, strongly interacting gases. Quantum sensors interfering superposition of two isotopes tested Universality...
