Disordered quantum spin chains with long-range antiferromagnetic interactions

Disordered quantum spin chains with long-range antiferromagnetic interactions
S. Kettemann, Hyun-Yong Lee, S. Haas, N. Moure, R. N. Bhatt
We investigate the magnetic susceptibility $χ(T)$ of quantum spin chains of $N=1280$ spins with power-law long-range antiferromagnetic couplings as a function of their spatial decay exponent $α$ and cutoff length $ξ$. The calculations are based on the strong disorder renormalization method which is ...
