Homework Statement
I'm supposed to show that whatever superposition of harmonic oscillator states is used to construct wavepacket of the form [tex]\sum[/tex] cv[tex]\Psi[/tex] (x,t) (cv are arbitary complex coefficients), it is at the same place at the times 0, T, 2T,.. where T = 2 [tex]\pi[/tex]/[tex]\omega[/tex]
Homework Equations
The Attempt at a Solution
I was thinking of using the position operator on the function and subbing t = 2n [tex]\pi[/tex]/[tex]\omega[/tex] as the time but i don't really know where to start
