Coarse graining as a representation change
We discuss how SU(1,1) coherent states from the discrete series allow for a natural coarse graining operation. The physical application is quantum theories based on a set of three extensive observables whose Poisson algebra is isomorphic to su(1,1). In particular, we show that a Perelomov coherent s...
