DYNAMICS OF ENTANGLEMENT IN OPTICAL CAVITIES
J. M. Herazo · 2007
The dynamics of one two-level atoms coupled to a lossy electromagnetic cavity, in the dispersive regime, is analyzed. A Lie algebraic technique is employed to find an analytic expression for the density operator and the linearized entropies of all systems and subsys- tems involved. Despite the infinite number of levels of the cavity electromagnetic field, which is initially prepared in a coherent state, it is shown that concurrence can be used to characterize entanglement
