Extinction of Populations and the Schrödinger Equation: Analytic Calculations for Abrupt Transitions

Niraj Kumar, V. M. Kenkre

We study bifurcations in a spatially extended nonlinear system representing population dynamics with the help of analytic calculations based on the time-independent Schrödinger equ…

Theory of possible effects of the Allee phenomenon on refugia of the Hantavirus epidemic

Niraj Kumar, M. N. Kuperman, V. M. Kenkre

We investigate possible effects of high order nonlinearities on the shapes of infection refugia of the Hantavirus epidemic. We replace Fisher-like equations that have been recently…

Nonlinearity in Bacterial Population Dynamics: Proposal for Experiments for the Observation of Abrupt Transitions in Patches

V. M. Kenkre, Niraj Kumar

An explicit proposal for experiments leading to abrupt transitions in spatially extended bacterial populations in a Petri dish is presented on the basis of an exact formula obtaine…

Front propagation in A2A, A3A process in 1d: velocity, diffusion and velocity correlations

Niraj Kumar, Goutam Tripathy

We study front propagation in the reaction diffusion process on a one dimensional (1d) lattice with hard core interaction between the…

Velocity of front propagation in the epidemic model

Niraj Kumar, Goutam Tripathy

We study front propagation in the irreversible epidemic model in one dimension. Here, we allow the particles and to diffuse with rates and , which, i…

Velocity and diffusion coefficient of reaction fronts in one dimension

Niraj Kumar, Goutam Tripathy

We study front propagation in the reversible reaction-diffusion system A + A <-> A on a 1-d lattice. Extending the idea of leading particle in studying the motion of the front we w…
