Differential cross sections for elastic and inelastic positronium-hydrogen-atom scattering
(American Physical Soc, 2001-05-01)
A time reversal symmetric regularized electron exchange model was used to elastic scattering, target elastic Ps excitations and target inelastic excitation of hydrogen in a five state coupled model. A singlet Ps-H-S-wave ...

Mean-field description of collapsing and exploding Bose-Einstein condensates
(2002-07-01)
Numerical simulations based on the time-dependent mean-field Gross-Pitaevskii equation was performed to explain the dynamics of collapsing and exploding Bose-Einstein condensates (BEC) of 85Rb atoms. The atomic interaction ...

Variational calculation of positronium-helium-atom scattering length
(2001-08-01)
A basis-set calculation scheme for S-waves Ps-He elastic scattering below the lowest inelastic threshold was formulated using a variational expression for the transition matrix. The scheme was illustrated numerically by ...

Interplay between radiation pressure force and scattered light intensity in the cooperative scattering by cold atoms
(Taylor and FrancisAbingdon, 2014-02)
The interplay between the superradiant emission of a cloud of cold two-level atoms and the radiation pressure force is discussed. Using a microscopic model of coupled atomic dipoles driven by an external laser, the radiation ...
