Hi, first of all thanks for your fast answer! But then.. as I said above, I'm totally lost in quantum physics, so I don't quite get your statement. I guess it's about part (a) of my assignment which shows the time evolution. But what happened to \varphi1 and \varphi2 ? I'm sorry for my obviously...
Hi, I'm totally lost here...Quantum physics seems to be just incomprehensible to me! Hope someone can help me out! That would be great!
Homework Statement
(a) A spin system with 2 possible states, described by
(E1 0)=H
