Abstract: (1643 Views)
In this paper, we study the entanglement of two level atoms near a spherical silver nanoparticle. By employing the Von Neumann equation and making use of the electromagnetic Green tensor associated with a dispersive and dissipative dielectric sphere, the decay rates and the Lamb shift of the atomic system are obtained. Then, by using the concurrence measure, we calculate the degree of entanglement of the atomic system. We observe that decay rates severely increase near the excitation frequency of the localized Polariton-Plasmons, while the concurrence value is nearly zero.
