Rotationally invariant multipartite states
Abstract
We construct a class of multipartite states possessing rotational SO(3) symmetry -- these are states of K spin-jA particles and K spin-jB particles. The construction of symmetric states follows our two recent papers devoted to unitary and orthogonal multipartite symmetry. We study basic properties of multipartite SO(3) symmetric states: separability criteria and multi-PPT conditions.
