Query: Crossover from Electromagnetically Induced Transparency to Autler-Townes
  Splitting in Open V-Type Molecular Systems   We investigate electromagnetically induced transparency (EIT) and
Autler-Townes splitting(ATS) in an open V-type molecular system. Through
detailed analytical calculations on the absorption spectrum of probe laser
field by using residue theorem and spectrum decomposition, we find that EIT may
occur and there exists a crossover from EIT to ATS (i.e. EIT-ATS crossover) for
hot molecules. However, there is no EIT and hence no EIT-ATS crossover for cold
molecules. Furthermore, we prove that for hot molecules EIT is allowed even for
a counter-propagating configuration. We provide explicit formulas of EIT
conditions and widths of EIT transparency windows of probe field when hot
molecules work in co-propagating and counter-propagating configurations,
respectively. Our theoretical result agrees well with the recent experimental
one reported by Lazoudis et al. [Phys. Rev. A 83, 063419 (2011)].
