Abstract:We study the interaction of a three two-level atoms (3-2LA) with a one-mode
op?tical coherent field in coherent state in the presence of non-linear Kerr
medium. The three atoms are initially prepared in upper and entangled states
while the field mode is in a coherent state. The constants of motion, 3-2LA
and field density matrix are obtained. The analytic results are employed to
perform some investigations of the temporal evolution of the von Neumann
entropy as measure of the degree of entang… Show more
