Integrated atom traps for quantum sensor applications — •Jorge Ferreras, Thomas Barrett, Anton Piccardo-Selg, Jessica Maclean, Christopher Mellor, Thomas Fernholz, Fedja Orucevic, and Peter Kruger — School of Physics and Astronomy, The University of Nottingham, UK

Trapping and cooling atoms close to surfaces broadens the horizon on quantum sensor applications. However, size has always been a constraint for making such devices. With new understructures and multi-layers chips, it is now possible to miniaturize this setups. A compact low-power consumption system can be used to routinely trap and cool atoms down to and below temperatures at which Bose-Einstein Condensation (BEC) occurs. We demonstrate how self-contained integrated structures are used to produce Rb BECs with power dissipation in the milliwatt range. Truly portable sensors based on ultracold gases are now being developed with a view to a wide range of industrial applications, including underground mapping and navigation.
