| Jul 28, 2019 at 1:05 | comment | added | Optimus Prime | @octonion, I'm asking about the infinitely degenerate classical vacua (the minima of the periodic potential). Perhaps I caused unwanted complication by bringing up theta and should have stuck with a shift symmetry of sorts | |

| Jul 26, 2019 at 19:47 | comment | added | octonion | Are you asking a question about purely classical configurations? What you refer to as vacua in your question (the states with a definite topological charge) are field configurations. But as John Dougherty's points out in his answer the quantum states are a superposition of states connected by large gauge transformations. | |
