Potential Energy Surface Database of Group II Dimer Molecules

December 1, 2003
Author(s)
Svetlana A. Kotochigova, Paul S. Julienne
The purpose of this work is to provide critical atomic and molecular data needed in order to evaluate the feasibility of using laser cooled and trapped Group II atomic species (Mg, Ca, Sr, and Ba) and Yb for ultra-precise optical clocks or quantum

Ab Initio Calculation of the KRb Dipole Moments

August 1, 2003
Author(s)
Svetlana A. Kotochigova, Paul S. Julienne, Eite Tiesinga
The relativistic configuration interaction valence bond method has been used to calculate permanent and transition electric dipole moments of the KRb heteronuclear molecule as a function of internuclear separation. The permanent dipole moment of the ground

Creation of a Dipolar Superfluid in Optical Lattices

March 1, 2003
Author(s)
B Damski, L Santos, E Tiemann, M Lewenstein, Svetlana A. Kotochigova, Paul S. Julienne, W.H. Zoller
We show that by loading a Bose-Einstein condensate (BEC) of two different atomic species into an optical lattice, it is possible to achieve a Mott-insulator phase with exactly one atom of each species per lattice site. A subsequent photo-association leads

Ultracold Collision Properties of Metastable Alkaline-Earth Atoms

February 1, 2003
Author(s)
A Derevianko, S. G. Porsev, Svetlana A. Kotochigova, Eite Tiesinga, Paul S. Julienne
Ultra-cold collisions of spin-polarized Mg, Ca, and Sr in the metastable 3P2 excited state are investigated. We show the existence of purely long-range potentials, determine the scattering length, and estimate the collisional loss rate as a function of

Precise Energies of Highly Excited Hydrogen and Deuterium

November 1, 2002
Author(s)
Svetlana A. Kotochigova, Peter J. Mohr, Barry N. Taylor
The energy levels of hydrogen and deuterium atoms are calculated to provide frequencies for transitions between highly excited states with principal quantum number n up to 200. All known quantum electrodynamics and relativistic corrections have been

Scattering Length of the Ground-State Mg+Mg Collision

April 1, 2002
Author(s)
Eite Tiesinga, Svetlana A. Kotochigova, Paul S. Julienne
We have constructed the $XA I \Sigma_g^+ $ potential for the collision between two ground state Mg atoms andanalyzed the effect of uncertainties in the shape of the potential on scattering properties at ultra-cold temperatures.This potential reproduces the
