Simulation of Spatial Systems with Demographic Noise
Haim Weissmann, Nadav M. Shnerb, David A. Kessler
Demographic (shot) noise in population dynamics scales with the square root of the population size. This process is very important, as it yields an absorbing state at zero field, b…
Empirical analysis of vegetation dynamics and the possibility of a catastrophic desertification transition
Haim Weissmann, Rafi Kent, Yaron Michael +1
The process of desertification in the semi-arid climatic zone is considered by many as a catastrophic regime shift, since the positive feedback of vegetation density on growth rate…
Fronts and fluctuations at a critical surface
Haim Weissmann, Nadav M. Shnerb, David A. Kessler
The properties of a front between two different phases in the presence of a smoothly inhomogeneous external field that takes its critical value at the crossing point is analyzed. T…
Predicting catastrophic shifts
Haim Weissmann, Nadav M. Shnerb
Catastrophic transitions, where a system shifts abruptly between alternate steady states, are a generic feature of many nonlinear systems. Recently these regime shift were suggeste…
Stochastic Desertification
Haim Weissmann, Nadav M. Shnerb
The process of desertification is usually modeled as a first order transition, where a change of an external parameter (e.g. precipitation) leads to a catastrophic bifurcation foll…
