Rank Statistics in Biological Evolution
E. Ben-Naim, P. L. Krapivsky
We present a statistical analysis of biological evolution processes. Specifically, we study the stochastic replication-mutation-death model where the population of a species may gr…
Polymerization with Freezing
E. Ben-Naim, P. L. Krapivsky
Irreversible aggregation processes involving reactive and frozen clusters are investigated using the rate equation approach. In aggregation events, two clusters join irreversibly t…
Velocity Distributions of Granular Gases with Drag and with Long-Range Interactions
K. Kohlstedt, A. Snezhko, M. V. Sapozhnikov +3
We study velocity statistics of electrostatically driven granular gases. For two different experiments: (i) non-magnetic particles in a viscous fluid and (ii) magnetic particles in…
Power-law velocity distributions in granular gases
E. Ben-Naim, B. Machta, J. Machta
We report a general class of steady and transient states of granular gases. We find that the kinetic theory of inelastic gases admits stationary solutions with a power-law velocity…
Percolation with Multiple Giant Clusters
E. Ben-Naim, P. L. Krapivsky
We study the evolution of percolation with freezing. Specifically, we consider cluster formation via two competing processes: irreversible aggregation and freezing. We find that wh…
