iTEBD results for small anisotropy \(a_K = a_\Gamma = 0.1\), and bond dimension χ = 10. a Néel order parameter MNéel, and ground state energy per site, E0/N. b Entanglement entropy S E associated with splitting the system along the different bonds in the eight-site unit cell. In most of the phase diagram all the strong z bonds are identical, and so are all the weak, x and y bonds. In the transition region near ϕ = 0.6π, the symmetry between like bonds is broken, perhaps indicating a first order transition. At ϕ/π = 0.75, the entanglement entropy vanishes since the system is in a product state. Inset: schematic of Cayley tree with z = 3 connectivity
