Nonreciprocal phase separation in living chiral crystal
ORAL
Abstract
Swimming starfish embryos spontaneously assemble into living crystals that span thousands of spinning organisms and persist for tens of hours. Carrying an arrow of time, the embryos spin in the counter clockwise manner and interact non-reciprocally with each other. As a result, this living chiral crystal exhibits many interesting phenomena from order-disorder transition to chiral waves. Here, we investigate the phase diagram of living chiral crystals formed by embryos from different developmental stages. We observe a number of different time dependent phases, from mixed to fully separated to coexisting phases.
