Short-time statistics of extinction and blowup in reaction kinetics
Rotem Degany, Michael Assaf, Baruch Meerson
We study the statistics of extinction and blowup times in well-mixed systems of stochastically reacting particles. We focus on the short-time tail, , of the extinction- or…
Impact of temporary lockdown on disease extinction in assortative networks
Elad Korngut, Michael Assaf
Changing environmental conditions can significantly affect the dynamics of disease spread. These changes may arise naturally or result from human interventions; in the latter case,…
Spatial correlations in SIS processes on random regular graphs
Alexander Leibenzon, Samuel W. S. Johnson, Ruth E. Baker +1
In network-based SIS models of infectious disease transmission, infection can only occur between directly connected individuals. This constraint naturally gives rise to spatial cor…
Large deviations in non-Markovian stochastic epidemics
Matan Shmunik, Michael Assaf
We develop a framework for non-Markovian, well-mixed SIR and SIS models beyond mean field, utilizing the continuous-time random walk formalism. Using a gamma distribution for the i…
Impact of network assortativity on disease lifetime in the SIS model of epidemics
Elad Korngut, Michael Assaf
To accurately represent disease spread, epidemiological models must account for the complex network topology and contact heterogeneity. Traditionally, most studies have used random…
Non-Markovian Rock-Paper-Scissors games
Ohad Vilk, Mauro Mobilia, Michael Assaf
There is mounting evidence that species interactions often involve long-term memory, with highly-varying waiting times between successive events and long-range temporal correlation…
Efficient weighted-ensemble network simulations of the SIS model of epidemics
Elad Korngut, Ohad Vilk, Michael Assaf
The presence of erratic or unstable paths in standard kinetic Monte Carlo simulations significantly undermines the accurate simulation and sampling of transition pathways. While ty…
Escape from a metastable state in non-Markovian population dynamics
Ohad Vilk, Michael Assaf
We study the long-time dynamics in non-Markovian single-population stochastic models, where one or more reactions are modelled as a stochastic process with a fat-tailed non-exponen…
An accurate reaction-diffusion limit to the spherical-symmetric Boltzmann equation
Shay I. Heizler, Menahem Krief, Michael Assaf
We resolve a long standing question regarding the suitable effective diffusion coefficient of the spherically-symmetric transport equation, which is valid at long times. To that en…
