Causal Entropic Forces: Dynamics and Pattern Formation — •Hannes Hornischer, Stephan Herminghaus, and Marco G. Mazza — MPI for Dynamics and Self-Organization, Göttingen

One basic principle of evolution is survival, that is, organisms distance themselves from situations threatening their physical health and thereby enlarge their accessible space of possible futures. We use a path-based entropy, causal entropy, which can be viewed as a measure for the diversity of future options, and examined the dynamics of a particle solely driven by a causal entropic force towards states of highest entropy production. Without any extra information about the system and solely due to entropic force those particles are able to adapt to changes in their environment, overcome potential barriers, find the fastest escape paths in evacuation scenarios. Many particles in a confined space would develop stable spatial patterns. This basic and general approach has the potential to give deeper understanding in social interactions in the context of behavioral ecology, for example applied to insects, fish or humans.
