NMR relaxation of quantum spin chains in magnetic fields
arXiv:cond-mat/0612008 · doi:10.1103/PhysRevB.74.172410
Abstract
We investigate NMR relaxation rates 1/T_1 of quantum spin chains in magnetic fields. Universal properties for the divergence behavior of 1/T_1 are obtained in the Tomonaga-Luttinger-liquid state. The results are discussed in comparison with experimental results.
