Multiscaling in Models of Magnetohydrodynamic Turbulence
Abhik Basu, Anirban Sain, Sujan K. Dhar +1
From a direct numerical simulation of the MHD equations we show, for the first time, that velocity and magnetic-field structure functions exhibit multiscaling, extended self simila…

Inertial- and Dissipation-Range Asymptotics in Fluid Turbulence
Sujan K. Dhar, Anirban Sain, Rahul Pandit
We propose and verify a wave-vector-space version of generalized extended self similarity and broaden its applicability to uncover intriguing, universal scaling in the far dissipat…

Nonequilibrium Phase Transitions in a Driven Sandpile Model
Sujan K. Dhar, Rahul Pandit, Sriram Ramaswamy
We construct a driven sandpile slope model and study it by numerical simulations in one dimension. The model is specified by a threshold slope $σ_c\/$, a parameter $α\/$, governing…
