Query: Role of dressed-state interference in electromagnetically induced
  transparency   Electromagnetically induced transparency (EIT) in three-level systems uses a
strong control laser on one transition to modify the absorption of a weak probe
laser on a second transition. The control laser creates dressed states whose
decay pathways show interference. We study the role of dressed-state
interference in causing EIT in the three types of three-level systems -- lambda
($\Lambda$), ladder ($\Xi$), and vee (V). In order to get realistic values for
the linewidths of the energy levels involved, we consider appropriate hyperfine
levels of $^{87}$Rb. For such realistic systems, we find that dressed-state
interference causes probe absorption---given by the imaginary part of the
susceptibility---to go to zero in a $\Lambda$ system, but plays a negligible
role in $\Xi$ and V systems.
