SUMMARY:Collective Atom-Photon Interactions toward a Hybrid Quantum Sy
 stem\, R. G. Herb Condensed Matter Seminar\, Jongmin Lee\,  Joint Quan
 tum Institute (JQI)\, University of Maryland
DESCRIPTION:The nanofiber-based optical lattices with a large optical 
 depth have been demonstrated for 87Rb atoms using two-color evanescent
  optical trapping fields of 750nm and 1064nm lights. 87Rb atoms in our
  lattices experience light shifts (to the blue) on 5P3/2 to all upper 
 transitions\, and the absorption profile is shifted to the blue. In ad
 dition\, the ellipticity of a HE11 mode leads to strong Zeeman broaden
 ing\, both on 5P3/2 and 5S1/2\, due to the vector light shifts. This i
 nhomogeneous broadening based on light shifts\, atomic temperature dis
 tribution\, and population redistribution was studied.<br>

\nIn
  addition\, a dual-wavelength high-finesse cavity system having homoge
 neous atom-cavity coupling and high cavity finesses (180\,000 for 780n
 m and 120\,000 for 1560nm) has been studied for the collective atom-ca
 vity interactions such as the spin-squeezing for atomic sensor applica
 tions\, the macroscopic self-trapping behavior (quantum simulation) to
 ward the macroscopic Schrodinger cat state generation\, and Raman lasi
 ng with atomic gain medium toward a sub-Hz linewidth laser will be add
 ressed.
