Electromagnetically Induced Transparency in an Atom-Molecule Bose-Einstein Condensate

We propose a new measurement scheme for the atom-molecule darkstate by using electromagnetically induced transparency (EIT)technique. Based on a density-matrix formalism, we calculate theabsorption coefficient numerically. The appearance of the EIT dipin the spectra profile gives clear evidence for the creation ofthe dark state in the atom-molecule Bose-Einstein condensate.
