Depinning of KPZ Interfaces in Fractional Brownian Landscapes
Neda Valizadeh, Morteza Nattagh Najafi
We explore the critical dynamics of driven interfaces propagating through a two dimensional disordered medium with long range spatial correlations, modeled using fractional Brownia…
Fractional Nonlinear Schrodinger Equation Revisited
Morteza Nattagh Najafi, Fatemeh Foroughirad
We investigate the space time fractional nonlinear Schrodinger equation (FNLSE) incorporating the modified Riemann Liouville derivative introduced by Jumari. The equation is charac…
Emergent Dynamical Ising Transition in Diffusive Sandpiles
Armin Makani, Morteza Nattagh Najafi
Minimally stable site (MSS) clusters play a dominant role in shaping avalanches in the self-organized critical (SOC) systems. The manipulation of MSS clusters through local smoothi…
Simulating Cumulus Clouds based on Self-Organized Criticality
J. Cheraghalizadeh, M. Luković, M. N. Najafi
Recently it was shown that self-organized criticality is an important ingredient of the dynamics of cumulus clouds (Physical Review E, 103(5), p.052106, 2021). Here we introduce a…
The effect of retardation in the random networks of excitable nodes embeddable in the Euclidean space
M. N. Najafi, M. Rahimi
Some features of random networks with excitable nodes that are embeddable in the Euclidean space are not describable in terms of the conventional integrate and fire model (IFM) alo…
Sandpile on uncorrelated site-diluted percolation lattice; From three to two dimensions
M. N. Najafi, H. Dashti-Naserabadi
The BTW sandpile model is considered on three dimensional percolation lattice which is tunned with the occupation parameter . Along with the three-dimensional avalanches, we stu…
Conformal symmetry of electron-hole puddles in ungated graphene
M. N. Najafi, M. Ghasemi Nezhadhaghighi
In this paper the mono-layer graphene at the charge neutrality point is considered whithin Thomas-Fermi-Dirac theory, treating inhomogeneous external potentials and electron-electr…
Fokker-Planck Equation of Schramm-Loewner Evolution
M. N. Najafi
In this paper we statistically analyze the Fokker-Planck (FP) equation of Schramm-Loewner evolution (SLE) and its variant SLE(). After exploring the derivation and the prope…
Bak-Tang-Wiesenfeld Model in the Finite Range Random Link Lattice
M. N. Najafi
We consider the BTW model in random link lattices with finite range interaction (RLFRI). The degree distribution for nodes is considered to be uniform in the interval . We…
Numerical Determination of Boundary Condition Changing Operators
M. N. Najafi
A new numerical method to determine the boundary condition changing (bcc) operators in the statistical models is introduced. This method is based on a variant of Schramm-Loewner Ev…
Avalanche frontiers in dissipative abelian sandpile model as off-critical SLE(2)
M. N. Najafi, Saman Moghimi-Araghi, S. Rouhani
Avalanche frontiers in Abelian Sandpile Model (ASM) are random simple curves whose continuum limit is known to be a Schramm-Loewner Evolution (SLE) with diffusivity parameter $κ= 2…
Observation of SLE on the Critical Statistical Models
M. N. Najafi, S. Moghimi-Araghi, S. Rouhani
Schramm-Loewner Evolution (SLE) is a stochastic process that helps classify critical statistical models using one real parameter . Numerical study of SLE often involves curves t…
