so I've been reading about the density operator formulation of quantum mechanics and I have some questions(adsbygoogle = window.adsbygoogle || []).push({});

what is the density operator analog of the schrodinger equation that determines the time evolution?

and how do you perform a projection measurement on a quantum system in the density operator formulation?

how would you use it to describe a system like the infinite square well?
