Comment on ‘‘Phase-sensitive population decay: The two-atom Dicke model in a broadband squeezed vacuum’’
Z. Ficek, P. D. Drummond · Physical Review A · 1990
A recent paper [G. M. Palma and P. L. Knight, Phys. Rev. A 39, 1962 (1989)] has stated that the two-atom Dicke model exhibits phase-dependent population decay. In this Comment we show that population decay is invariant with respect to the input phase angle of squeezing in the two-atom Dicke model.
