Processos Paramétricos em eletrodinâmica quântica de cavidades.
(Universidade Federal de São Carlos, 2004-03-02)
In this thesis we study the interaction between an atom and a cavity mode submitted
to linear and parametric amplifications. The evolution operator of the system was derived
through the technique of time-dependent ...
Processos quânticos em cavidades com a geometria variável.
(Universidade Federal de São Carlos, 2004-03-11)
In this thesis, we study the quantum de ection of ultracold particles by mirrors, the shrinking of free wave packets, the tunnelling of narrow Gaussian packets through delta potentials and the entanglement between the modes ...
Estudo dos efeitos de colisões atômicas na dinâmica, nas propriedades estatíticas e no emaranhamento entre átomos aprisionados interagindo com a luz.
(Universidade Federal de São Carlos, 2005-03-10)
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 ...
