Extinction in population dynamics
C. Escudero, J. Buceta, F. J. de la Rubia +1
We study a generic reaction-diffusion model for single-species population dynamics that includes reproduction, death, and competition. The population is assumed to be confined in a…
Comprehensive study of phase transitions in relaxational systems with field-dependent coefficients
J. Buceta, Katja Lindenberg
We present a comprehensive study of phase transitions in single-field systems that relax to a non-equilibrium global steady state. The mechanism we focus on is not the so-called St…
Pulse Velocity in a Granular Chain
Alexandre Rosas, Katja Lindenberg
We discuss the applicability of two very different analytic approaches to the study of pulse propagation in a chain of particles interacting via a Hertz potential, namely, a contin…
Pulse Propagation in Chains with Nonlinear Interactions
Alexandre Rosas, Katja Lindenberg
Pulse propagation in nonlinear arrays continues to be of interest because it provides a possible mechanism for energy transfer with little dispersion. Here we show that common meas…
Self-Similarity in Random Collision Processes
Daniel ben-Avraham, Eli Ben-Naim, Katja Lindenberg +1
Kinetics of collision processes with linear mixing rules are investigated analytically. The velocity distribution becomes self-similar in the long time limit and the similarity fun…
Drift by Dichotomous Markov Noise
I. Bena, C. Van den Broeck, R. Kawai +1
We derive explicit results for the asymptotic probability density and drift velocity in systems driven by dichotomous Markov noise, including the situation in which the asymptotic…
