Logarithmic corrections to gap scaling in random-bond Ising strips
نویسنده
چکیده
Numerical results for the first gap of the Lyapunov spectrum of the selfdual random-bond Ising model on strips are analysed. It is shown that finite-width corrections can be fitted very well by an inverse logarithmic form, predicted to hold when the Hamiltonian contains a marginal operator.

Weak versus strong universality in the two-dimensional random-bond Ising ferromagnet.
We address the issue of universality in two-dimensional disordered Ising systems, by considering long, finite-width strips of ferromagnetic Ising spins with randomly distributed couplings. We calculate the free energy and spin-spin correlation functions ~from which averaged correlation lengths, j, are computed! by transfer-matrix methods. An ansatz for the size dependence of logarithmic correct...
متن کاملLogarithmic corrections to correlation decay in two-dimensional random-bond Ising systems.
The statistics of critical spin-spin correlation functions in Ising systems with nonfrustrated disorder are investigated on a strip geometry, via numerical transfer-matrix techniques. Conformal invariance concepts are used, in order to test for logarithmic corrections to pure power-law decay against distance. Fits of our data to conformal-invariance expressions, specific to logarithmic correcti...
متن کاملCritical behavior of the pure and random-bond two-dimensional triangular Ising ferromagnet.
We investigate the effects of quenched bond randomness on the critical properties of the two-dimensional ferromagnetic Ising model embedded in a triangular lattice. The system is studied in both the pure and disordered versions by the same efficient two-stage Wang-Landau method. In the first part of our study, we present the finite-size scaling behavior of the pure model, for which we calculate...
متن کاملThe Site-Diluted Ising Model in Four Dimensions
In the literature, there are five distinct, fragmented sets of analytic predictions for the scaling behaviour at the phase transition in the random-site Ising model in four dimensions. Here, the scaling relations for logarithmic corrections are used to complete the scaling pictures for each set. A numerical approach is then used to confirm the leading scaling picture coming from these predictio...
متن کاملLogarithmic corrections in the two-dimensional Ising model in a random surface field
According to scaling theory, when quenched disorder is coupled to the surface order parameter in the two-dimensional Ising model, the random surface field is a marginally irrelevant perturbation. We study the boundary critical behaviour of the above system through extensive Monte Carlo simulations. Logarithmic corrections to the surface critical behaviour of the pure system are identified in ag...
