Schramm-Loewner evolution in the random scatterer Henon-percolation landscapes
M. N. Najafi, S. Tizdast, J. Cheraghalizadeh
The Shcramm-Loewner evolution (SLE) is a correlated exploration process, in which for the chordal set up, the tip of the trace evolves in a self-avoiding manner towards the infinit…
Fillips in Sandpiles; Spanning Avalanches, Bifurcation and Temporal oscillations
M. N. Najafi, Z. Moghadam
The manipulation of the self-organized critical systems by repeatedly deliberate local relaxations (fillips) affect considerably the dynamics of avalanches and change their evoluti…
Correlation effects in the diluteness pattern in non-integral dimensional systems on superdiffusion process
J. Cheraghalizadeh, M. N. Najafi
The effect of the correlations in the diluteness pattern in the systems with non-integral dimensionality, on superdiffusion process is considered in this paper. The…
Gaussian Free Field in the iso-height random islands tuned by percolation model
J. Cheraghalizadeh, M. N. Najafi, H. Mohammadzadeh
The Gaussian free field (GFF) is considered in the background of random iso-height islands which is modeled by the site percolation with the occupation probability . To realize…
Thermodynamic Geometry of Normal (Exotic) BTZ Black Hole Regarding to the Fluctuation of Cosmological Constant
Hosein Mohammadzadeh, Maryam Rastkar, Morteza Nattagh Najafi
We construct the thermodynamic geometry of dimensional normal (exotic) BTZ black hole regarding to the fluctuation of cosmological constant. We argue that while the thermodyn…
Scaling properties of mono-layer graphene away from the Dirac point
M. N. Najafi, N. Ahadpour, J. Cheraghalizadeh +1
The statistical properties of the carrier density profile of graphene in the ground state in the presence particle-particle interaction and random charged impurity in zero gate vol…
Gaussian Free Field in the background of correlated random clusters, formed by metallic nanoparticles
J. Cheraghalizadeh, M. N. Najafi, H. Mohammadzadeh
The effect of metallic nano-particles (MNPs) on the electrostatic potential of a disordered 2D dielectric media is considered. The disorder in the media is assumed to be white-nois…
Percolation transition in two dimensional electron gas: A quantum cellular automaton model
M. N. Najafi
A new type of disorder-driven electronic percolation transition is found for two-dimensional electron gas (2DEG), based on a quantum cellular automaton model. This transition is sh…
Interaction-disorder-driven characteristic momentum in graphene, approach of multi-body distribution functions
M. N. Najafi
Multi-point probability measures along with the dielectric function of Dirac Fermions in mono-layer graphene containing particle-particle and white-noise (out-plane) disorder inter…
Statistical Investigation of Avalanches of Three Dimensional Small-World Networks and their Boundary and Bulk Cross-Sections
M. N. Najafi, H. Dashti-Naserabadi
In many situations we are interested in the propagation of energy in some portions of a three dimensional system with dilute long-range links. In this paper sandpile model is defin…
Self-Avoiding Walk on the square site-diluted Ising-correlated lattice
J. Cheraghalizadeh, M. N. Najafi, H. Mohammadzadeh +1
The self-avoiding walk on the square site-diluted correlated percolation lattice is considered. The Ising model is employed to realize the spatial correlations of the metric space.…
Power spectrum of rare events in two-dimensional BTW model, violation of noise hypothesis
Z. Moghadam, M. N. Najafi, A. Saber +1
One of the primitive aims of the two-dimensional BTW model had been to explain the noise which is widely seen in the natural systems. In this paper we study some time signa…
