Bi-partite and global entanglement in a many-particle system with collective spin coupling
R. G. Unanyan, C. Ionescu, M. Fleischhauer
Bipartite and global entanglement are analyzed for the ground state of a system of spin 1/2 particles interacting via a collective spin-spin coupling described by the Lipkin-Me…

Quantum Electrodynamics in Media with Negative Refraction
Jürgen Kästel, Michael Fleischhauer
We consider the interaction of atoms with the quantized electromagnetic field in the presence of materials with negative index of refraction. Spontaneous emission of an atom embedd…

Sub- and super-radiance over macroscopic distances using a perfect lens with negative refraction
Juergen Kaestel, Michael Fleischhauer
Two atoms put at the foci of a perfect lens [J.B. Pendry, Phys. Ref. Lett. 85, 3966 (2000)] are shown to exhibit perfect sub- and super-radiance even over macroscopic distances lim…
