Phase space of dynamic, adaptive colloidal crystals far from equilibrium

ORAL

Abstract

We explored the expansive phase space of a driven dissipative colloidal system, defined exclusively by physical dynamics and absent any chemical, magnetic, electrical, or direct optical interactions. This configurational landscape encompasses a rich variety of periodic and quasi-periodic crystals alongside superhomogeneous disordered hyperuniform structures. The phase space undergoes significant transformation within highly nonlinear and strongly stochastic regimes, giving rise to evolving potential energy surfaces. Our experimental findings are substantiated through comprehensive computational analysis, allowing us to calculate occurrence and transition probabilities and elucidate the system's energetics.
