Local and Non-local Fractional Porous Media Equations
Fatemeh Gharari, Karina Arias-Calluari, Fernando Alonso-Marroquin +1
Recently it was observed that the probability distribution of the price return in S\&P500 can be modeled by -Gaussian distributions, where various phases (weak, strong super dif…
Self-organized criticality in cumulus clouds
M. N. Najafi, J. Cheraghalizadeh, H. J. Herrmann
The shape of clouds has proven to be essential for classifying them. Our analysis of images from fair weather cumulus clouds reveals that, besides by turbulence they are driven by…
The intermediate fermionic species created by rotation in the representation of the Dirac equation
H. Moaiery, M. N. Najafi
The question of how does the Dirac equation depend on the choice of the matrices has partially been addressed and explored in the literature. In this paper we focus on this que…
Some Properties of Sandpile Models as Prototype of Self-Organized Critical Systems
M. N. Najafi, S. Tizdast, J. Cheraghalizadeh
This paper is devoted to the recent advances in self-organized criticality (SOC), and the concepts. The paper contains three parts; in the first part we present some examples of SO…
Two temperature Ising Model
J. Cheraghalizadeh, M. Seifi, Z. Ebadi +2
We introduce a two-temperature Ising model as a prototype of superstatistic critical phenomena. The model is described by two temperatures () in zero magnetic field. To pr…
Invasion Sandpile Model
M. N. Najafi, Z. Moghaddam, M. Samadpour +1
Motivated by multiphase flow in reservoirs, we propose and study a two-species sandpile model in two dimensions. A pile of particles becomes unstable and topples if, at least one o…
Dynamical Crossover in Invasion Percolation
S. Tizdast, N. Ahadpour, M. N. Najafi +2
The dynamical properties of the invasion percolation on the square lattice are investigated with emphasis on the geometrical properties on the growing cluster of infected sites. Th…
