What is a minimum sized wavepacket

  1. Jan 3, 2008 #1
    I've read a few texts where the term "minimum sized wavepacket" is used. Can anyone explain what the "minimum size" refers to in the context of a wavepacket? Thanks.

    They are probably referring to a wave packet for which
    [twx]\Delta k\Delta x[/tex] is a minimum. This is a Gaussian wave packet:
    [tex]f(x,t)=N\exp\left[-(x-x_0)^2/a^2\right]\exp[-i(k_0 x-\omega_0 t][/tex].
