Ground State Properties of an S=1/2 Distorted Diamond Chain
Takashi Tonegawa, Kiyomi Okamoto, Toshiya Hikihara +2
We investigate the ground state properties of an S=1/2 distorted diamond chain described by the Hamiltonian ${\cal H}=J_1\sum_\ell\bigl\{\bigl(\vecS_{3\ell-1}\cdot\vecS_{3\ell} +\v…

Numerical renormalization-group study of spin correlations in one-dimensional random spin chains
T. Hikihara, A. Furusaki, M. Sigrist
We calculate the ground-state two-spin correlation functions of spin-1/2 quantum Heisenberg chains with random exchange couplings using the real-space renormalization group scheme.…
