Homework Help: Derivation of a coupled differential equation

  1. May 27, 2012 #1
    1. The problem statement, all variables and given/known data
    I would like to understand how the coupled differential equation in http://physics.schooltool.nl/quantumoptics/images/content/rabi/eqn12.gif [Broken] is derived from the equation http://physics.schooltool.nl/quantumoptics/images/content/rabi/eqn11.gif [Broken]. I got the equations from the below.

    3. The attempt at a solution

    In the first link, when you multiply the term with |e><e| with the terms in 2nd parenthesis it seems to me its multiplication with first term in the second parenthesis equals 0, as dot product of <e| and |g> must equal zero.
