Invading activity fronts stabilize excitable systems against stochastic extinction
Kenneth A. V. Distefano, Sara Shabani, Uwe C. Täuber
Stochastic chemical reaction or population dynamics in finite systems often terminates in an absorbing state. Yet in large spatially extended systems, the time to reach species ext…
Stochastic spatial Lotka-Volterra predator-prey models
Uwe C. Täuber
Stochastic, spatially extended models for predator-prey interaction display spatio-temporal structures that are not captured by the Lotka-Volterra mean-field rate equations. These…
Non-universal critical aging scaling in three-dimensional Heisenberg antiferromagnets
Riya Nandi, Uwe C. Täuber
We numerically investigate the stationary and non-equilibrium critical dynamics in three-dimensional isotropic Heisenberg antiferromagnets. Since the non-conserved staggered magnet…
Boundary Effects on Population Dynamics in Stochastic Lattice Lotka-Volterra Models
Bassel Heiba, Sheng Chen, Uwe C. Täuber
We investigate spatially inhomogeneous versions of the stochastic Lotka-Volterra model for predator-prey competition and coexistence by means of Monte Carlo simulations on a two-di…
Population oscillations in spatial stochastic Lotka-Volterra models: A field-theoretic perturbational analysis
Uwe C. Tauber
Field theory tools are applied to analytically study fluctuation and correlation effects in spatially extended stochastic predator-prey systems. In the mean-field rate equation app…
Stochastic population oscillations in spatial predator-prey models
Uwe C. Tauber
It is well-established that including spatial structure and stochastic noise in models for predator-prey interactions invalidates the classical deterministic Lotka-Volterra picture…
