SUMMARY:RF Spectroscopy of Optically Trapped Lithium : Magic Polarizat
 ion.\, Atomic Physics Seminar\, Huidong Kim\, Korea University
DESCRIPTION:An optical dipole trap for alkali metal atoms is one of th
 e most useful ways for a precision spectroscopy and a quantum informat
 ion processing (QIP). We are interested in eliminating differential ac
 -Stark shift of atoms in the optical trap between the two ground hyper
 fine levels to obtain narrow line width and long coherence time. We st
 udy the polarization dependence of the Stark shift via vector polariza
 bility and controlled the polarization of the trapping field. We carry
  out a hyperfine spectroscopy between two ground hyperfine states . We
  expect that the magic polarization brings breakthroughs in precision 
 measurement and quantum information processing.&lt\;br&gt\;<br><br>
