movie1.mov: Low-density quench of a system of N=8000 Active Brownian Hard Disks with PBC from (\phi=0.5,\,\mbox{Pe}=60) to (\phi=0.12,\,\mbox{Pe}=60). The system remains phase separated well below the onset of MIPS, but above the coexistence line, as expected from the thermodynamic description of first-order phase transitions. movie2.avi: Evolution of a system of N=3000 Active Brownian WCA Particles with PBC from an homogenous configuration (low-Pe quench) at \mbox{Pe}=90 and \phi=0.35. The evolution of the interaction and active contribution to the virial pressure is also shown by green and blue lines respectively.
