Phase diagram of the anisotropic spin-2 XXZ model: Infinite-system density matrix renormalization group study
We study the ground state phase diagram of the quantum spin-2 XXZ chain in the presence of on-site anisotropy using a matrix-product state based infinite system density-matrix-renormalization-group (iDMRG) algorithm. One of the interests in this system is in connecting the highly quantum mechanical spin-1 phase diagram with the classical S=infinity …
