Here, the authors present a novel scheme to study dynamical phase transitions (DPTs) from topological edge states in the Su-Schrieffer-Heeger model. They utilize eight coupled nanomechanical oscillators to simulate the quantum quenches and observe DPTs via directly measuring the Pancharatnam geometric phase in the experiment. The robustness of the DPT and its relation to equilibrium phases are explored. This nanomechanical lattice with its multiple modes, high quality factor, and temporal configurability offers unique advantages for research into nonequilibrium phenomena via an artificial solid-state platform.
