Abstract

We construct a class of multipartite states possessing rotational SO(3) symmetry --- these are states of K spin-j A particles and K spin-j B 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.
