Nonequilibrium Phase Transition in a Model of Diffusion, Aggregation and Fragmentation
Satya N. Majumdar, Supriya Krishnamurthy, Mustansir Barma
We study the nonequilibrium phase transition in a model of aggregation of masses allowing for diffusion, aggregation on contact and fragmentation. The model undergoes a dynamical p…
Dynamic exponent in Extremal models of Pinning
S. Krishnamurthy, A. Tanguy, S. Roux
The depinning transition of a front moving in a time-independent random potential is studied. The temporal development of the overall roughness w(L,t) of an initially flat front, $…
A Stochastic Description for Extremal Dynamics
S. Krishnamurthy, A. Tanguy, P. Abry +1
We show that extremal dynamics is very well modelled by the "Linear Fractional Stable Motion" (LFSM), a stochastic process entirely defined by two exponents that take into account…
Bubbling and Large-Scale Structures in Avalanche Dynamics
Supriya Krishnamurthy, Vittorio Loreto, Stephane Roux
Using a simple lattice model for granular media, we present a scenario of self-organization that we term self-organized structuring where the steady state has several unusual featu…
