Guiding atoms into hollow fibre with attractive optical guide LightPhilip HiltonAshby 2018 Experimental and simulated movies of atoms being optically guided into HC-PCF.<div>The cloud of 100 million atoms at 3uK is released from the MOT, and falls under gravity. Atoms within the optical dipole trap with low enough energy are guided into the hollow core fibre, generating extremely large optical depths.</div>
