| Dec 12, 2018 at 3:57 | comment | added | Chiral Anomaly | I'm glad you posted this. It makes an important point, namely that the states selected by decoherence depend on the circumstances. Another thought: Both of our "answers" cite sources that use a separation of the system into two parts, whose details we do and don't (respectively) care about, and we typically take a partial trace to hide the latter. I view this as a simplified version of what we'd really like to do, which is to separate the set of observables into those that are and are not (respectively) feasibly measureable, with only a fuzzy line between them. But that complicates the math. | |
