Model of periodically pulsating elliptical particles yields a phase diagram of collective states and a hydrodynamic description that qualitatively reproduces the main microscopic behaviors.
A mechanochemical model of 1D active solids coupled to Hopf oscillators reveals symmetry-protected phases and a compression-driven oscillation death transition classifiable by group theory.
