We report a numerical study of the bond-diluted two-dimensional Potts model using transfer-matrix calculations. For different numbers of states per spin, we show that the critical exponents at the random fixed point are the same as in self-dual random-bond cases. In addition, we determine the multifractal spectrum associated with the scaling dimensions of the moments of the spin-spin correlation function in the cylinder geometry. We show that the behaviour is fully compatible with the one…

Monte Carlo study of the triangular Blume-Capel model under bond randomness.
The results verify previous renormalization-group calculations on the Blume-Capel model with disorder in the crystal-field coupling and find evidence that, the second-order transition emerging under bond randomness from the first-order regime of the pure model, belongs again to the same universality class.
Harris-Luck criterion for random lattices
The Harris-Luck criterion judges the relevance of (potentially) spatially correlated, quenched disorder induced by, e.g., random bonds, randomly diluted sites, or a quasiperiodicity of the lattice,
Symmetry relations for multifractal spectra at random critical points
Random critical points are generically characterized by multifractal properties. In the field of Anderson localization, Mirlin et al (2006 Phys. Rev. Lett. 97 046803) have proposed that the
Smeared spin-flop transition in random antiferromagnetic Ising chain
At T = 0 and in a sufficiently large field, the nearest-neighbor antiferromagnetic Ising chain undergoes a first-order spin-flop transition into the ferromagnetic phase. We consider its smearing
Random cascade models of multifractality: real-space renormalization and travelling waves
Random multifractals occur in particular at critical points of disordered systems. For Anderson localization transitions, Mirlin and Evers (2000 Phys. Rev. B 62 7920) have proposed the following
Pure and random quantum Ising chain: Shannon and Rényi entropies of the ground state via real space renormalization
The Shannon and the Renyi entropies of the ground state wavefunction in the pure and in the random quantum Ising chain are studied via the self-dual Fernandez–Pacheco real-space renormalization
Many-body-localization transition: strong multifractality spectrum for matrix elements of local operators
For short-ranged disordered quantum models in one dimension, the Many-Body-Localization is analyzed via the adaptation to the Many-Body context [M. Serbyn, Z. Papic and D.A. Abanin, PRX 5, 041047
Statistical properties of the Green function in finite size for Anderson localization models with multifractal eigenvectors
For Anderson Localization models with multifractal eigenvectors on disordered samples containing $N$ sites, we analyze in a unified framework the consequences for the statistical properties of the

Abstract The theory of large deviations is already the natural language for the statistical physics of equilibrium and non-equilibrium. In the field of disordered systems, the analysis via large


Short-Time Dynamics of Random-Bond Potts Ferromagnet with Continuous Self-Dual Quenched Disorders*
We present our Monte Carlo results of the random-bond Potts ferromagnet with the Olson–Young self-dual distribution of quenched disorders in two dimensions. By exploring the short-time scaling
Magnetic critical behavior of two-dimensional random-bond Potts ferromagnets in confined geometries.
A numerical study of two-dimensional random-bond Potts ferromagnets, and the critical behavior is investigated through conformal invariance techniques that were recently shown to be valid, even in the randomness-induced second-order phase transition regime Q>4.
The effect of quenched impurities on systems which undergo first-order phase transitions is studied within the framework of the q-state Potts model. For large q a mapping to the random field Ising
Finite-size scaling study of two-dimensional dilute Potts models
The author uses transfer matrices to calculate the free energy and various thermodynamic quantities of the two- and three-state Potts models with random bond interactions at the critical temperature.
Finite-Size Scaling Study of the Surface and Bulk Critical Behavior in the Random-Bond Eight-State Potts Model
The self-dual random-bond eight-state Potts model is studied numerically through large-scale Monte Carlo simulations using the Swendsen-Wang cluster flipping algorithm. We compute bulk and surface

Numerically examine the large-q asymptotics of the q-state random bond Potts model and finds that the central charge seems to behave like c(q)=1 / 2 log(2)(q)+O(1).
