Interpretation of probability which includes complex number!

  1. Nov 28, 2008 #1
    Hi everybody!

    I'm trying to find the probability at time t of finding the state pointing in the positive x-direction of an initial system which points in the negative x-direction. I'm not sure if the result is correct, but I get the probability is sin^2(iwt). Can this be understood as the frequency w is a complex number? And what is complex frequency? Or if the frequency is not a complex number, how can I understand the result?

    Thanks for your help!

    ps: the problem is similar to the example Spin Precession in Sakurai book (page 75), but with complex number in the probability.

    Maybe you can provide more details about the calculation, so we can help.
