ello everybody,(adsbygoogle = window.adsbygoogle || []).push({});

how can I calculate the group velocity of a wave package in an infinite square well?

I know only how it can be calculated with a free particle, the derivation of the dispersion relation at the expectation value of the moment.

But in the well, there are only discrete values of k allowed.

It would help a lot if someone could send me a link or give a little help,

thanks
