Boundary critical behaviour of two-dimensional random Ising models
F. Igloi, P. Lajko, W. Selke +1
Using Monte Carlo techniques and a star-triangle transformation, Ising models with random, 'strong' and 'weak', nearest-neighbour ferromagnetic couplings on a square lattice with a…

Exact Renormalization-Group Study of Aperiodic Ising Quantum Chains and Directed Walks
F. Igloi, L. Turban, D. Karevski +1
We consider the Ising model and the directed walk on two-dimensional layered lattices and show that the two problems are inherently related: The zero-field thermodynamical properti…
