Coherent population trapping in quantized light field
A. V. Taichenachev, A. M. Tumaikin, V. I. Yudin
abstract: A full quantum treatment of coherent population trapping (CPT) is given for a
system of resonantly coupled atoms and electromagnetic field. We develop a
regular analytical method of the construction of generalized dark states (GDS).
It turns out that GDS do exist for all optical transitions $F_g\to F_e$,
including bright transitions $F\to F+1$ and $F''\to F''$ with $F''$ a
half-integer, for which the CPT effect is absent in a classical field. We
propose an idea to use an optically thick medium with a transition $F''\to F''$
with $F'' \ge 3/2$ a half-integer as a ''quantum filter'', which transmits only
a quantum light.
