Scaling and universality in the phase diagram of the 2D Blume-Capel model
J. Zierenberg, N. G. Fytas, M. Weigel +2
We review the pertinent features of the phase diagram of the zero-field Blume-Capel model, focusing on the aspects of transition order, finite-size scaling and universality. In par…
Restoration of dimensional reduction in the random-field Ising model at five dimensions
Nikolaos G. Fytas, Victor Martin-Mayor, Marco Picco +1
The random-field Ising model is one of the few disordered systems where the perturbative renormalization group can be carried out to all orders of perturbation theory. This analysi…
Specific-heat exponent and modified hyperscaling in the 4D random-field Ising model
N. G. Fytas, V. Martin-Mayor, M. Picco +1
We report a high-precision numerical estimation of the critical exponent of the specific heat of the random-field Ising model in four dimensions. Our result indica…
Cluster Monte Carlo and dynamical scaling for long-range interactions
Emilio Flores-Sola, Martin Weigel, Ralph Kenna +1
Many spin systems affected by critical slowing down can be efficiently simulated using cluster algorithms. Where such systems have long-range interactions, suitable formulations ca…
Self-averaging in the random 2D Ising ferromagnet
Victor Dotsenko, Yurij Holovatch, Maxym Dudka +1
We study sample-to-sample fluctuations in a critical two-dimensional Ising model with quenched random ferromagnetic couplings. Using replica calculations in the renormalization gro…
Gyrokinetic turbulence: between idealized estimates and a detailed analysis of nonlinear energy transfers
Bogdan Teaca, Frank Jenko, Daniel Told
Using large resolution numerical simulations of GK turbulence, spanning an interval ranging from the end of the fluid scales to the electron gyroradius, we study the energy transfe…
