Critical Behavior of the Ferromagnetic Ising Model on a Sierpiński Carpet: Monte Carlo Renormalization Group Study
نویسندگان
چکیده
We perform a Monte Carlo Renormalization Group analysis of the critical behavior of the ferromagnetic Ising model on a Sierpiński fractal with Hausdorff dimension df ≃ 1.8928. This method is shown to be relevant to the calculation of the critical temperature Tc and the magnetic eigen-exponent yh on such structures. On the other hand, scaling corrections hinder the calculation of the temperature eigen-exponent yt. At last, the results are shown to be consistent with a finite size scaling analysis. Keyword: MCRG, fractal, phase transition, critical exponents. PACS: 64.60.Ak Renormalization-group, fractal, and percolation studies of phase transitions 75.10.Hk Classical spin models

Critical and multicritical behavior of the ±J Ising model in two and three dimensions
We report our Monte Carlo results on the critical and multicritical behavior of the ±J Ising model [with a random-exchange probability P (Jxy) = pδ(Jxy−J)+(1−p)δ(Jxy +J)], in two and three dimensions. We study the transition line between the paramagnetic and ferromagnetic phase, which extends from p = 1 to a multicritical (Nishimori) point. By a finitesize scaling analysis, we provide strong nu...
متن کاملIsing model on a hyperbolic plane with a boundary.
A hyperbolic plane can be modeled by a structure called the enhanced binary tree. We study the ferromagnetic Ising model on top of the enhanced binary tree using the renormalization-group analysis in combination with transfer-matrix calculations. We find a reasonable agreement with Monte Carlo calculations on the transition point, and the resulting critical exponents suggest the mean-field surf...
متن کاملInfinite-randomness quantum Ising critical fixed points
We examine the ground state of the random quantum Ising model in a transverse field using a generalization of the Ma-Dasgupta-Hu renormalization group ~RG! scheme. For spatial dimensionality d52, we find that at strong randomness the RG flow for the quantum critical point is towards an infinite-randomness fixed point, as in one dimension. This is consistent with the results of a recent quantum ...

A critical review is given of status and perspectives of Monte Carlo simulations that address bulk and interfacial phase transitions of ferromagnetic Ising models. First, some basic methodological aspects of these simulations are brie#y summarized (single-spin #ip vs. cluster algorithms, "nite-size scaling concepts), and 0370-1573/01/$ see front matter 2001 Elsevier Science B.V.

متن کاملNon-equilibrium relaxation and interface energy of the Ising model
From the non-equilibrium critical relaxation study of the two-dimensional Ising model, the dynamical critical exponent z is estimated to be 2.165 ± 0.010 for this model. The relaxation in the ordered phase of this model is consistent with exp(− √ t/τ ) behavior. The interface energy of the threedimensional Ising model is studied and the critical exponent of the correlation length ν and the crit...
