Non-radiative density matrix EOM

  1. Feb 28, 2012 #1
    Dear all, Could anyone please explain to me for a 3 level syste, coupled with 2 lasers, what is the equation describing the disspative term of the equation of motion of the density matrix? I am looking for a non-radiative decay, namely the overall population should conserved.

    I have found this article, on equation 4.4, it looks like answered my question, but very confused with the notation it used.


    thank you so much in advance.
