DESCRIPTION:Zoom-only seminar\n\nActive systems are made of in
 teracting units converting an energy source into s
 ustained dynamics\, yielding emergent states witho
 ut any equilibrium equivalent. In assemblies of se
 lf-propelled particles\, such as motile bacteria\,
  activity drives individual displacement. In dense
  biological tissues\, where crowding hinders motio
 n\, activity instead mostly drives individual puls
 ation\, namely periodic change in size. We examine
  active systems where the competition between puls
 ation\, synchronisation\, and steric hindrance tri
 ggers wave propagation without migration: Particle
  size undergoes collective oscillations with only 
 negligible particle displacement. This instability
  leads to a plethora of dynamical patterns akin to
  reaction-diffusion dynamics\, suggesting that pul
 sating active matter captures the same Physics des
 pite the absence of any reaction.
