In active systems, phase separation can be induced by a variety of mechanisms. In the Vicsek model, velocity alignment mediates the formation of clusters and phase separation in the form of polar bands. In self-propelled disk (SPD) systems, repulsive interactions lead to what has been called as motility-induced phase separation. For self-propelled rods, torques and forces lead to a phase separation process distinct from the one observed in the Vicsek model or SPD. Here, combining simulations and mean-field calculations, we demonstrate how the interplay of attraction and velocity-alignment interaction leads to a variety of phase separation processes and unveils two novel types of condensation classes.
Note the unusual day of the week (Tuesday).
Coffee and cookies will be served 15 minutes before the start of the seminar
