Agent-based Monte Carlo simulations for reaction-diffusion models, population dynamics, and epidemic spreading
Mohamed Swailem, Ulrich Dobramysl, Ruslan Mukhamadiarov +1
We provide an overview of Monte Carlo algorithms based on Markovian stochastic dynamics of interacting and reacting many-particle systems not in thermal equilibrium. These agent-ba…
Perturbative Field-Theoretical Analysis of Three-Species Cyclic Predator-Prey Models
Louie Hong Yao, Mohamed Swailem, Ulrich Dobramysl +1
We apply a perturbative Doi--Peliti field-theoretical analysis to the stochastic spatially extended symmetric Rock-Paper-Scissors (RPS) and May--Leonard (ML) models, in which three…
Computational methods and fast hybrid stochastic simulations for triangulation sensing and identifying principles of cell navigation in the brain
Ulrich Dobramysl, David Holcman
Brownian simulations can be used to generate statistics relevant for studying molecular interactions or trafficking. However, the concurrent simulation of many Brownian trajectorie…
Reconstructing a point source from diffusion fluxes to narrow windows in three dimensions
U. Dobramysl, D. Holcman
We develop a computational approach to locate the source of a steady-state gradient of diffusing particles from the fluxes through narrow windows distributed either on the boundary…
Critical Scaling and Aging near the Flux Line Depinning Transition
Harshwardhan Chaturvedi, Ulrich Dobramysl, Michel Pleimling +1
We utilize Langevin molecular dynamics simulations to study dynamical critical behavior of magnetic flux lines near the depinning transition in type-II superconductors subject to r…
Stochastic population dynamics in spatially extended predator-prey systems
Ulrich Dobramysl, Mauro Mobilia, Michel Pleimling +1
Spatially extended population dynamics models that incorporate intrinsic noise serve as case studies for the role of fluctuations and correlations in biological systems. Including…
