Realization of a superconducting atom chip
arXiv:quant-ph/0610019 · doi:10.1103/PhysRevLett.97.200405
Abstract
We have trapped rubidium atoms in the magnetic field produced by a superconducting atom chip operated at liquid Helium temperatures. Up to atoms are held in a Ioffe-Pritchard trap at a distance of 440 m from the chip surface, with a temperature of 40 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.
