Numerical Renormalization Group at Criticality
arXiv:cond-mat/9601078 · doi:10.1016/0375-9601(96)00128-4
Abstract
We apply a recently developed numerical renormalization group, the corner-transfer-matrix renormalization group (CTMRG), to 2D classical lattice models at their critical temperatures. It is shown that the combination of CTMRG and the finite-size scaling analysis gives two independent critical exponents.
