Universalities in ultracold reactions of alkali-metal polar molecules

We consider ultracold collisions of ground-state heteronuclear alkali-metal dimers that are susceptible to four-center chemical reactions 2AB → A2 + B2 even at submicrokelvin temperatures. These reactions depend strongly on species, temperature, electric field, and confinement in an optical lattice. We calculate ab initio van der Waals coefficients for these interactions and use a quantum forma...

Fe b 20 01 High - precision calculations of van der Waals coefficients for heteronuclear alkali - metal dimers

Van der Waals coefficients for the heteronuclear alkali-metal dimers of Li, Na, K, Rb, Cs, and Fr are calculated using relativistic ab initio methods augmented by high-precision experimental data. We argue that the uncertainties in the coefficients are unlikely to exceed about 1%.

Universal ultracold collision rates for polar molecules of two alkali-metal atoms.

Universal collision rate constants are calculated for ultracold collisions of two like bosonic or fermionic heteronuclear alkali-metal dimers involving the species Li, Na, K, Rb, or Cs. Universal collisions are those for which the short range probability of a reactive or quenching collision is unity such that a collision removes a pair of molecules from the sample. In this case, the collision r...

Spin relaxation in alkali - metal 1 S g ¿ dimers

We discuss the relaxation of a spin-polarized alkali-metal vapor due to the electric-quadrupole interaction in Sg 1 dimers, and present a model that accurately describes the measured relaxation rates under a wide variety of conditions. We use the model along with experimental results to deduce the quadrupole interaction strength, atom-dimer chemical-exchange reaction rate, and the rate of reori...

Chain structure and electronic states of liquid Rb-Se mixtures by ab initio molecular-dynamics simulations

The effects of excess electronic charges transferred from alkali metals to Se atoms on the chain structure in liquid RbxSe1−x for x 0.5 are investigated by means of ab initio molecular-dynamics simulations. It is found that the interaction between Se chains is enhanced by the transferred electrons, and that the average length of Se chains becomes shorter with increasing alkali-metal concentrati...
