So when the pulse of light is at the same frequency (wavelength) as the atomic resonance of the super cooled matter (the frequency of the atoms natural shimmy, which in a super cooled state act as a single, massive atom), the time (when measured as the amount of quantum state change as a result of the photon passing through the atomic medium) in which it traverses the atom is less than what it should be, indicating that the photon was not slowed in any way through it’s interaction with the atom(s).

…is that right? did I do an understanding?
