Numerical renormalization group study of random transverse Ising models in one and two space dimensions
Y. -C. Lin, N. Kawashima, F. Igloi +1
The quantum critical behavior and the Griffiths-McCoy singularities of random quantum Ising ferromagnets are studied by applying a numerical implementation of the Ma-Dasgupta-Hu re…
Random antiferromagnetic quantum spin chains: Exact results from scaling of rare regions
F. Igloi, R. Juhasz, H. Rieger
We study XY and dimerized XX spin-1/2 chains with random exchange couplings by analytical and numerical methods and scaling considerations. We extend previous investigations to dyn…
Correlation length-exponent relation for the two-dimensional random Ising model
Peter Lajko, Ferenc Igloi
We consider the two-dimensional (2d) random Ising model on a diagonal strip of the square lattice, where the bonds take two values, , with equal probability. Using an iter…
Boundary critical behaviour of two-dimensional random Potts models
Gábor Palágyi, Christophe Chatelain, Bertrand Berche +1
We consider random q-state Potts models for on the square lattice where the ferromagnetic couplings take two values with equal probabilities. For any q the…
Two-dimensional Dilute Ising Models: Defect Lines and the Universality of the Critical Exponent ν
Ferenc Szalma, Ferenc Igloi
We consider two-dimensional Ising models with randomly distributed ferromagnetic bonds and study the local critical behavior at defect lines by extensive Monte Carlo simulations. B…
