Realization of a superconducting atom chip
Thomas Nirrengarten, Angie Qarry, Cédric Roux, Andreas Emmert, Gilles Nogues, Michel Brune, Jean-Michel Raimond, Serge Haroche
abstract: We have trapped rubidium atoms in the magnetic field produced by a
superconducting atom chip operated at liquid Helium temperatures. Up to
$8.2\cdot 10^5$ atoms are held in a Ioffe-Pritchard trap at a distance of 440
$\mu$m from the chip surface, with a temperature of 40 $\mu$K. The trap
lifetime reaches 115 s at low atomic densities. These results open the way to
the exploration of atom--surface interactions and coherent atomic transport in
a superconducting environment, whose properties are radically different from
normal metals at room temperature.
