Traveling waves in a chemorepulsive active particle system — •Samuel Grimm, Fabian Bergmann, Lisa Rapp, and Walter Zimmermann — Theoretische Physik I, Universität Bayreuth, 95440 Bayreuth, Germany

A chemorepulsive active particle system may give rise to a bifurcation to spatially periodic traveling waves (TWs), whereby the density of active particles is conserved. Traveling waves in conserved systems show modified nonlinear dynamics compared to TWs in unconserved systems. The envelopes of these TWs also obey different generic model equations. We compare simulations of the continuum equations for the active particle systems to simulations of reduced generic equations. This comparison allows for the identification of generic properties of TWs in a chemorepulsive active particle system.
