Dissipative solitons and crowdions in triangular lattice of active particles

Behavior of dissipative solitons and crowdions in the triangular lattice of interacting particles is studied by means of numerical simulations. Active properties of particles are determined by non-linear friction which slows down the rapid particles and accelerates slower ones. Local interaction between particles is determined by the modified Morse potential with established cut-off radius. It is shown that the excitation of crowdions in active lattice is possible for some definite values of parameters. Borderlines between crowdions and solitons excitation in a space of parameters and initial conditions are determined.
