Dinâmica de coerência e decoerência de estados em redes de osciladores quânticos dissipativos.
(Universidade Federal de São Carlos, 2004-07-02)
In this thesis we studied the coherence and decoherence dynamics of states in
a network of dissipative quantum oscillators. The coherence dynamics refers to
the swap and recurrence process of states between the oscillators ...
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 ...
