Title: High precision spectroscopy of CS2 and RbCS molecules
Date/Time: 02 Jun, 02:00 PM
Venue: CQT Level 3 Seminar Room, S15-03-15
Ultracold molecules provide novel possible applications in many areas of physics ranging from precision measurement to quantum computing, few body physics, and physical chemistry. The techniques that up to now have produced molecules in ultracold temperature range mainly are magnetoassociation(MA) and photoassociation (PA). PA spectroscopy of ultracold atoms has become a powerful tool for investigation of the so-called long-range homonuclear and heteronuclear molecules with classical outer turning points of several to hundreds of nanometers. We study the ultracold long-range Cs2 molecules by carrying out three-dimensional modulation PA spectroscopy. We represent the potential curve with Cs2 spectroscopy by analytical asymptotic approach. Values of the radiative lifetimes of the 6p2P1/2 and 6p2P3/2 Cs atomic levels and van der waals coefficient C6 of ground state are obtained. Ultracold polar heteronuclear molecules are of particular interest because they interact strongly with applied electric fields for their permanent electric dipole moments (EDM) and the dipole-dipole intramolecular interactions are long-range, anisotropic, and tunable. We also investigate PA formation of the RbCs molecules in the (2)3Π state with a high sensitivity. We extract the corresponding rotational constant and centrifugal distortion constant based on a nonrigid model from the measured PA spectroscopy and assign the observed short-range molecular state.
