Fixation in Competing Populations: Diffusion and Strategies for Survival
Tapas Singha, Prasad Perlekar, Mustansir Barma
How should dispersal strategies be chosen to increase the likelihood of survival of a species? We obtain the answer for the spatially extended versions of three well-known models o…

Clustering, intermittency and scaling for passive particles on fluctuating surfaces
Tapas Singha, Mustansir Barma
We show that a scaling approach successfully characterizes clustering and intermittency in space and time, in systems of noninteracting particles driven by fluctuating surfaces. We…
