DESCRIPTION:\n	We study a one-dimensional system of Brownian particles tha
 t interact among themselves through local velocity-lignment forces that ar
 e discrete in time and do not affect the particle speed. The local veloci
 ty-alignment acts periodically over the system with time period t_a and pr
 obability P= t_a/t_0\, with t_0 being a control parameter. Depending on th
 e relation between t_a and t_0\, the velocity-alignment can affect all of
  the particles synchronously in time or just a few asynchronously. In any 
 case\, as the velocity-alignment events become more frequent\, the system 
 is driven from stationary states close to thermal equilibrium\, to far-fro
 m-equilibrium ones where the system exhibits spontaneous symmetry breaking
  and self-organization. Therefore\, our results show that self-propulsion
  is not a necessary ingredient to produce the flocking transition even in
  one-dimensional systems. Above the critical point\, for the synchronous c
 ase\, the velocity distribution of the particles exhibits periodic oscilla
 tions in time with period t_a\, and their density distribution shows a bre
 athing-like behavior. The effects of these phenomena produce a regular sp
 iking activity in the order parameter as the system approaches to the ther
 modynamic limit.\n\n//indico.ictp.it/event/11388/
