Colisões atômicas controladas em eletrodinâmica quântica de cavidades : emaranhamento como medida da classicalidade do campo de radiação
Resumo
In this dissertation we presente a study on the entanglement between two identical and noninteracting
two-level atoms, generated by their interaction with only a singl cavity filed mode.
We also show how to calculate the intensity of correlation between thes atoms by Concurrence.
Besides, was show the entanglement evolution for different field states and parameters for these
states in two intaraction regimes: ressonant and dispersive, showing numerically how the
maximum entanglement evolves form one regime to other for each cavity filed state. We are
also abble to identify wich parameters influence the intensity and shape of entanglement,
allowing us to define a non-classicality criterion for the radiation field.
