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…
