I've worked through a Stern Gerlach experiment for the Sx and Sz directions using the density matrix formalism to account for the environment. This shows a result which I was surprised at for Sx but I think it is correct but relies on decoherence to give the "actual" value. I'm not confident about the result though. Would anyone be kind enough to check my reasoning and conclusions please? Working is attached.
