Critical dynamics of ballistic and Brownian particles in a heterogeneous environment
Felix Höfling, Tobias Munk, Erwin Frey +1
The dynamic properties of a classical tracer particle in a random, disordered medium are investigated close to the localization transition. For Lorentz models obeying Newtonian and…
Noise and Correlations in a Spatial Population Model with Cyclic Competition
Tobias Reichenbach, Mauro Mobilia, Erwin Frey
Noise and spatial degrees of freedom characterize most ecosystems. Some aspects of their influence on the coevolution of populations with cyclic interspecies competition have been…
Microtubule dynamics depart from wormlike chain model
Katja M. Taute, Francesco Pampaloni, Erwin Frey +1
Thermal shape fluctuations of grafted microtubules were studied using high resolution particle tracking of attached fluorescent beads. First mode relaxation times were extracted fr…
Anomalous finite-size effects in the Battle of the Sexes
Jonas Cremer, Tobias Reichenbach, Erwin Frey
The Battle of the Sexes describes asymmetric conflicts in mating behavior of males and females. Males can be philanderer or faithful, while females are either fast or coy, leading…
Mobility promotes and jeopardizes biodiversity in rock-paper-scissors games
Tobias Reichenbach, Mauro Mobilia, Erwin Frey
Biodiversity is essential to the viability of ecological systems. Species diversity in ecosystems is promoted by cyclic, non-hierarchical interactions among competing populations.…
On the Role of Zealotry in the Voter Model
M. Mobilia, A. Petersen, S. Redner
We study the voter model with a finite density of zealots--voters than never change opinion. For equal numbers of zealots of each species, the distribution of magnetization (opinio…
