Query: Self-organization of bacterial mixtures in the presence of
  quorum-sensing interactions   We study analytically and numerically the self-organization of mixtures of
run-and-tumble bacteria whose motilities are regulated by quorum-sensing
interactions. We show the emergence of rich spatial structures, including
static and dynamic patterns. We derive a microscopic condition for restoring
action-reaction at the macroscopic scale, which endows the system with an
effective free energy functional. The latter allows us to rationalize the
static patterns observed in our simulations and to predict the corresponding
phase diagram. In the presence of non-reciprocal interactions, we derive a
sufficient condition to observe the emergence of travelling patterns.
