Ultracold scattering processes in three-atomic helium systems [PDF]
, 2007 We review results on scattering observables for $^4$He--$^4$He$_2$ and $^3$He--$^4$He$_2$ collisions. We also study the effect of varying the coupling constant of the atom-atom interaction on the scattering ...

Theory of an optical dipole trap for cold atoms [PDF]
, 2000 The theory of an atom dipole trap composed of a focused, far red-detuned, trapping laser beam, and a pair of red-detuned, counterpropagating, cooling beams is developed for the simplest realistic multilevel dipole interaction scheme based on a model of a

Signal tracking beyond the time resolution of an atomic sensor by Kalman filtering [PDF]
, 1998 We study causal waveform estimation (tracking) of time-varying signals in a paradigmatic atomic sensor, an alkali vapor monitored by Faraday rotation probing.

Bound States and Scattering Processes in the ^4He_3 Atomic System [PDF]
, 1997 We present a mathematically rigorous method for solving three-atomic bound state and scattering problems. The method is well suited for applications in systems where the inter-atomic interaction is of a hard-core nature.

Mixing Study in an Unbaffled Stirred Precipitator Using LES Modelling
International Journal of Chemical Engineering, 2012 This paper describes the CFD modelling of a reactor operating in the nuclear industry using LES approach. The reactor consists of an unbaffled stirred tank reactor in which plutonium precipitation reactions are carried out.
