Description:
Author(s): M. Cerezo, R. Rossignoli, N. Canosa, and E. Ríos We analyze ground state (GS) factorization in general arrays of spins s i with X X Z couplings immersed in nonuniform fields. It is shown that an exceptionally degenerate set of completely separable symmetry-breaking GSs can arise for a wide range of field configurations, at a quantum critical point wh... [Phys. Rev.
