| Sep 1, 2015 at 3:01 | comment | added | Timaeus | In general it's a bad idea to say the square is the probability density. You want to get the correct dynamics which will include eventually getting the frequency of results from repeated interactions with an ensemble of subsystems. But calling it a probability right away can lead to problems if you start to do it too much. For instance if you do it with position then you have to stop you can't do it with position and spin. To get the correlations right then spin had to sometimes be determined by position and by context if you assign position by regular probabilities. | |
| Sep 1, 2015 at 2:28 | comment | added | Gold | I imagined that, although the book I'm studying doesn't make it explicit. In that case, one should consider the configuration space $Q$ as we do in classical mechanics and then $\psi : Q\to \mathbb{C}$ will be such that $|\psi|^2$ is the probability density that the system is in the neighborhood of a certain configuration? | |
