主　　题：Active particle Anisotropic interaction Swarming 

摘      要：From the organization of animal flocks to the emergence of swarming behaviors in bacterial suspension,populations of motile organisms at all scales display coherent collective *** studies showed that the anisotropic interaction between active particles plays a key role in the phase *** we investigate the collective behaviors of based-active Janus particles that experience an anisotropic interaction of which the orientation is opposite to the direction of active force by using Langevin dynamics simulations in two dimensional ***,the system shows emergence of collective swarming states upon increasing the total area fraction of particles,which is not observed in systems without anisotropic interaction or *** threshold for emergence of swarming states decreases as particle activity or interaction strength *** have also performed basic kinetic analysis to reproduce the essential features of the simulation *** results demonstrate that anisotropic interactions at the individual level are sufficient to set homogeneous active particles into stable directed motion.
