Peculiarities of the dynamics of the atom-molecular conversion stimulated by Gauss pulses

Abstract

The study of the properties of cold and ultracold molecular gases at temperatures of a few micro- or nanokelvin is one of the most promising scientific directions in atomic and molecular physics and physical chemistry. Advances in controlling the interaction of ultracold atoms raise the question about the possibility of achieving such control for ultracold molecules as well. Therefore, further investigations of physical processes involving Bose condensed particles are of current interest both in theoretical and practical aspects. Below, we present the results of studying of stimulated Raman atom–molecular conversion under the action of two resonance laser pulses in a mixture of two different atoms with the formation of heteromolecules in the condensate.
