Estudo dos efeitos de colisões atômicas na dinâmica, nas propriedades estatíticas e no emaranhamento entre átomos aprisionados interagindo com a luz.

Abstract

In this work we consider a trapped Bose-Einstein Condensate interacting simultaneously with a high quality cavity quantized field and a classical undepleted laser field. Collisions between atoms are taken into account by a delta type contact potential. A linearized model is obtained which take into account simultaneous amplification of atomic and optical fields. We analyse the effects of atomic collisions on the system stability and statistical properties. Also is done a study of the degree of entanglement between atomic and optical fields.
