Real-Space Renormalization Group Study of Effects of Anisotropy on S=1 Random Antiferromagnetic Chain

Shigeru Koikegami, Synge Todo, Hajime Takayama

We investigate S=1 antiferromagnetic quantum spin chain, whose exchange couplings are strongly disordered. By the real-space renomalization group method, introduced by Ma, Dasgupta…
