Entanglement of an Atom and Its Spontaneous Emission Fields via Spontaneously Generated Coherence
(University of Tehran, 2011-06-01)The entanglement between a ?-type three-level atom and its spontaneous emission fields is investigated. The effect of spontaneously generated coherence (SGC) on entanglement between the atom and its spontaneous emission ...

An Entanglement Study of Superposition of Qutrit Spin-Coherent States
(University of Tehran, 2011-06-01)Considering generalized concurrence as the criterion of entanglement, we study entanglement properties of superposition of two qutrit coherent states, as a function of their amplitudes. These states may attain maximum ...
