"Spin-specific AC Zeeman potentials"


Seth Aubin , William & Mary
[Host: Cass Sackett]
ABSTRACT:

Spin-specific trapping and mechanical control of ultracold atoms is difficult with current techniques, but offers the possibility of exploring new physics systems, notably spin-dependent trapped atom interferometers, as well as quantum gates, 1D many-body spin gases, and novel cooling schemes. Microwave near-field potentials based on the AC Zeeman effect provide a mechanism for such spin-specific control of atoms: in principle, independent potentials can be targeted to different spin states simultaneously. We present recent experimental progress in implementing such control by using AC near-fields on an atom chip to drive hyperfine transitions and manipulate ultracold rubidium atoms.
