We show that by negative friction the system can be driven far from the thermodynamic equilibrium states. For over-critical pumping with free energy several types of coherent motions including uniform rotations, optical oscillations and waves emerge in the ring. We also show the existence of a critical particle density n(c) = N/L-c, below that the particles spontaneously organize into clusters which can actively rotate. Additionally, the influence of white noise on the clustering is discussed.engjournal articlehttp://www.worldscientific.com/doi/pdf/10.1142/S0218127402005923http://www.worldscientific.com/restricted access517.9Nonlinear frictionActive Brownian particlesLennard-Jones-like interactionsCluster formationBrownian particlesEnergy depotsTodaExcitationSolitonsLatticeEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
