SUMMARY:Vector light shift in optical atomic magnetometers with alkali
  atoms\, Atomic Physics Seminar\,  Lena Zhivun\, Berkeley
DESCRIPTION:Optical atomic magnetometers are among the most precise ma
 gnetic sensors today\, reaching sensitivities up to 0.16 fT/sqrt(Hz). 
 While the AC Stark effect is one of the noise sources in atomic magnet
 ometers\, it can be utilized to improve these devices. The effect of t
 he vector part of the AC Stark operator on alkali atoms is equivalent 
 to applying a magnetic field in the direction of the light propagation
 . We use this effect to create an all-optical vector magnetometer with
  0.2 pT/sqrt(Hz) sensitivity to the field magnitude and 4 mrad/sqrt(Hz
 ) sensitivity to the field direction\, as well as a scalar magnetomete
 r driven by a fictitious rf field with 40 fT/sqrt(Hz) sensitivity.
