Homework Help: Calculating velocity

  1. Mar 1, 2014 #1
    1. Hey,

    so I have a Lorentz violating wavepacket and from this I need to find the velocity.

    My wavepacket is of the form

    \langle\varphi(t,x)\rangle \equiv\exp\Bigg[i\textbf{K}_M(t-x)-\frac{\Delta\textbf{K}_M}{4}(t-x)^2\Bigg]

    where for this question you need to know that


    I did this:


    I only need to calculate v from the first term in the exponent and dt=dx and v=dx/dt and it must be of the form 1+...
