Establishment of an entangled atom-field state in the Jaynes-Cummings model
Simon J. D. Phoenix, P. L. Knight · Physical Review A · 1991
We use the eigenstates of the reduced density operators to give an explicit form of the entangled atom-field state in the Jaynes-Cummings model. We relate the expansion coefficients to physical quantities and discuss the effect of atomic coherence on this entangled state.
