SUMMARY:Steady-state switching and dispersion/absorption spectroscopy 
 of multilevel atoms inside an optical ring cavity\, Atomic Physics Sem
 inar\, Jiteng Sheng\, University of Arkansas
DESCRIPTION:Electromagnetically induced transparency (EIT) is essentia
 l in coherent atomic physics\, which has been extensively studied in t
 he last two decades. The important properties of EIT are its steep nor
 mal linear dispersion and greatly enhanced nonlinearity with a negligi
 ble absorption near atomic resonance. When EIT medium is placed inside
  an optical cavity\, many interesting effects can occur. In this talk\
 , I will discuss several experiments in EIT-related atom-cavity system
 s. Particular attention will be given to nonlinear optical cavity tran
 smission spectra and optical multistate switching with Doppler-broaden
 ed multilevel atoms inside an optical ring cavity. In addition\, parit
 y-time symmetry and optically induced lattice in EIT-related medium wi
 ll be briefly discussed.
