“…Active matter systems coupled to periodic substrates have been studied with a variety of simulations and experiments in both the single particle and collective limits [39][40][41][42][43][44][45]. Computational work on interacting systems has even shown that an active matter commensuration or Mott effect can occur in which for some fillings the active particles form an ordered MIPS state that is strongly pinned to the substrate, while for other fillings there is a more mobile active cluster glass phase [46].…”

We investigate the transport of interacting active run-and-tumble particles moving under an external drift force through a periodic array of obstacles for increasing drive amplitudes. For high activity where the system forms a motility induced phase separated state, there are several distinct dynamic phases including a low drive pinned cluster phase, an intermediate uniform ﬂuid, and a higher drive stripe crystal state. The transitions between the phases are correlated with signatures in the transport curves, differential mobility, and power spectra of the velocity ﬂuctuations. In contrast, in the low activity regime the transport curves and power spectra undergo little change as a function of drive. We argue that in the high activity limit, the behavior is similar to that of driven solids on periodic substrates, while in the low activity limit the system behaves like a driven ﬂuid.
