Trapping and manipulating neutral atoms with electrostatic fields Academic Article uri icon


  • We report on experiments with cold thermal $^{7}\mathrm{L}\mathrm{i}$ atoms confined in combined magnetic and electric potentials. A novel type of three-dimensional trap was formed by modulating a magnetic guide using electrostatic fields. We observed atoms trapped in a string of up to six individual such traps, a controlled transport of an atomic cloud over a distance of $400\text{ }\text{ }\ensuremath{\mu}\mathrm{m}$, and a dynamic splitting of a single trap into a double well potential. Applications for quantum information processing are discussed.
