Numerical analysis of homogeneous and inhomogeneous intermittent search strategies
Karsten Schwarz, Yannick Schröder, Heiko Rieger
A random search is a stochastic process representing the random motion of a particle (denoted as the searcher) that is terminated when it reaches (detects) a target particle or are…
Optimality of spatially inhomogeneous search strategies
Karsten Schwarz, Yannick Schröder, Bin Qu +2
We consider random search processes alternating stochastically between diffusion and ballistic motion, in which the distribution function of ballistic motion directions varies from…
Efficient kinetic Monte Carlo method for reaction-diffusion processes with spatially varying annihilation rates
Karsten Schwarz, Heiko Rieger
We present an efficient Monte Carlo method to simulate reaction-diffusion processes with spatially varying particle annihilation or transformation rates as it occurs for instance i…
Domain walls and chaos in the disordered SOS model
K. Schwarz, A. Karrenbauer, G. Schehr +1
Domain walls, optimal droplets and disorder chaos at zero temperature are studied numerically for the solid-on-solid model on a random substrate. It is shown that the ensemble of r…
