Demixing of two species via reciprocally concentration-dependent diffusivity
Lutz Schimansky-Geier, Benjamin Lindner, Sebastian Milster +1
We propose a model for demixing of two species by assuming a density-dependent effective diffusion coefficient of the particles. Both sorts of microswimmers diffuse as active overd…
Variability of collective dynamics in random tree networks of strongly-coupled stochastic excitable elements
Ali Khaledi-Nasab, Justus A. Kromer, Lutz Schimansky-Geier +1
We study the collective dynamics of strongly diffusively coupled excitable elements on small random tree networks. Stochastic external inputs are applied to the leaves causing larg…
Search and Return Model for Stochastic Path Integrators
J. Noetel, V. L. S. Freitas, E. E. N. Macau +1
We extend a recently introduced prototypical stochastic model describing uniformly the search and return of objects looking for new food sources around a given home. The model desc…
Optimal Noise in a Stochastic Model for Local Search
J. Noetel, V. L. S. Freitas, E. E. N. Macau +1
We develop a prototypical stochastic model for local search around a given home. The stochastic dynamic model is motivated by experimental findings of the motion of a fruit fly aro…
Adiabatic elimination of inertia of the stochastic microswimmer driven by stable noise
Joerg Noetel, Igor M. Sokolov, Lutz Schimansky-Geier
We consider a microswimmer that moves in two dimensions at a constant speed and changes the direction of its motion due to a torque consisting of a constant and a fluctuating compo…
Stochastic Dynamics of Resistive Switching: Fluctuations Lead to Optimal Particle Number
Paul K. Radtke, Andrew L. Hazel, Arthur V. Straube +1
Resistive switching is one of the foremost candidates for building novel types of non-volatile random access memories. Any practical implementation of such a memory cell calls for…
