Two-dimensional Ising model with self-dual biaxially correlated disorder
F. A. Bagamery, L. Turban, F. Igloi
We consider the Ising model on the square lattice with biaxially correlated random ferromagnetic couplings, the critical point of which is fixed by self-duality. The disorder repre…
Logarithmic corrections in the two-dimensional Ising model in a random surface field
M. Pleimling, F. A. Bagamery, L. Turban +1
In the two-dimensional Ising model weak random surface field is predicted to be a marginally irrelevant perturbation at the critical point. We study this question by extensive Mont…
Surface-induced disorder and aperiodic perturbations at first-order transitions
L. Turban, F. Igloi
In systems displaying a bulk first-order transition the order parameter may vanish continuously at a free surface, a phenomenon which is called surface-induced disorder. In the pre…
Critical behaviour near multiple junctions and dirty surfaces in the two-dimensional Ising model
F. Igloi, L. Turban, B. Berche
We consider m two-dimensional semi-infinite planes of Ising spins joined together through surface spins and study the critical behaviour near to the junction. The m=0 limit of the…
Critical behaviour in parabolic geometries
I. Peschel, L. Turban, Ferenc Igloi
We study two-dimensional systems with boundary curves described by power laws. Using conformal mappings we obtain the correlations at the bulk critical point. Three different class…
Conformal Profiles in the Hilhorst--van Leeuwen Model
D. Karevski, L. Turban, F. Igloi
We study the critical energy and magnetization profiles for the Ising quantum chain with a marginal extended surface perturbation of the form A/y, y being the distance from the sur…
