Resumo

We study the dynamics of nonclassical correlations of an atom interacting with a squeezed coherent state or a squeezed coherent states superposition (SCSS) trapped into a lossy thermal cavity QED by using local quantum uncertainty (LQU). By varying several parameters of control, such as the average photon number of the coherent state and the squeezing parameter, we are able to select the atom–field interaction time allowing us to obtain the higher value to LQU. In addition, after the atom leaving the cavity, for certain range of the displacement parameter we have found a sudden change in the LQU as a function of time when the squeezing parameter of the SCSS is very small.
