Mf. Fang et Gh. Zhou, INFLUENCE OF ATOMIC COHERENCE ON THE EVOLUTION OF FIELD ENTROPY IN MULTIPHOTON PROCESSES, Physics letters. A, 184(6), 1994, pp. 397-402
The influence of atomic coherence on the evolution of field entropy in
multiphoton processes is examined. It is shown that the evolution of
the field entropy is dependent on the relative phase of atom and field
.
