- I posted something recently explaining why rotational symmetry causes there
- to be wave-functions that change by only +/- 1 under 360 degree rotations.
- But how does this mix with how the wave-function has to change when you
- take two identical particles and switch them? After all, the two-particle
- system doesn't have the SO(3) symmetry anymore, just O(2).
-
- (And am I thinking right that "two identical particles" means "two
- equivalent irreducible representations of the underlying symmetry group
- of the physics"? And that people discovering additional quantum numbers
- is equivalent to them extending their group? There seem to be so many
- more books out there to explain math to physicists than physics to
- mathematicians : -8 ( Allen K.
