Phys. Rev. B 29, 4026–4029 (1984)Domain-wall renormalization-group study of the two-dimensional random Ising modelReceived 16 December 1983; published in the issue dated 1 April 1984 The distribution of domain-wall free energies is calculated with the use of a transfer-matrix approach for finite lattices. A renormalization-group transformation is set up which preserves the domain-wall free-energy distribution as well as the susceptibility when the lattice parameter is changed. The fixed points, critical exponents, and phase diagram are determined for the two-dimensional random Ising model with a Gaussian distribution of nearest-neighbor interactions. © 1984 The American Physical Society URL:
