Supplementary movies for Stability of discrete-symmetry flocks: sandwich state, traveling domains and motility-induced pinning, Phys. Rev. E 112, 064115 (2025). A preprint is available on arXiv

The details about each movie are given in the pdf document "movie_details.pdf". 

  • movie 01 - The file movie01_APM_hydrodynamics.mp4 shows the time evolution obtained from the hydrodynamic equations of a counter-propagating droplet and a transversely-propagating droplet inserted in an ordered state.
  • movie 02 - The file movie02_APM_droplet_rectangular.mp4 shows the time evolution of a counter-propagating droplet and a transversely-propagating droplet inserted in an ordered state in a rectangular domain.
  • movie 03 - The file movie03_APM_droplet_counter_beta=1.mp4 shows the time evolution of a counter-propagating droplet inserted in an ordered state at low temperature for several velocity.
  • movie 04 - The file movie04_APM_droplet_counter_beta=0.75.mp4 shows the time evolution of a counter-propagating droplet inserted in an ordered state at high temperature for several velocity.
  • movie 05 - The file movie05_APM_droplet_transverse.mp4 shows the time evolution of a transversely-propagating droplet inserted in an ordered state for several velocity.
  • movie 06 - The file movie06_APM_droplet_D=0.3.mp4 shows the time evolution of a counter-propagating droplet and a transversely-propagating droplet inserted in an ordered state for D=0.3.
  • movie 07 - The file movie07_APM_droplet_D=0.2.mp4 shows the time evolution of a counter-propagating droplet and a transversely-propagating droplet inserted in an ordered state for D=0.2 and several velocities.
  • movie 08 - The file movie08_APM_droplet_D=0.1.mp4 shows the time evolution of a counter-propagating droplet and a transversely-propagating droplet inserted in an ordered state for D=0.1 and several velocities.
  • movie 09 - The file movie09_APM_spontaneous_flock.mp4 shows the fate of the ordered state in a short range state and a stripe state.
  • movie 10 - The file movie10_APM_spontaneous_MIP.mp4 shows the formation of the motility-induced (interface) pinning starting from an ordered state.
  • movie 11 - The file movie11_APM_droplet_MIP.mp4 shows a counter-propagating droplet pinning starting from an ordered state.
