James Martin: Atom chips and Rydberg atoms

James Martin, University of Waterloo

Abstract

"Atom chips" allow the manipulation of ultra-cold laser cooled atoms using micro fabricated wire structures. Current carrying wires on the chip surface generate inhomogeneous magnetic fields, allowing cold atoms to be held by the same forces as those in the famous Stern-Gerlach experiment. By varying the wire currents atoms can be squeezed into small volumes, and put at specific distances relative to surfaces.
