A wide range of experimental systems including gliding, swarming and swimming bacteria,
in vitro motility assays, and shaken granular media are commonly described as self …

Living systems operate far from thermodynamic equilibrium. Enzymatic activity can induce
broken detailed balance at the molecular scale. This molecular scale breaking of detailed …

The opportunistic pathogen Pseudomonas aeruginosa explores surfaces using twitching
motility powered by retractile extracellular filaments called type IV pili (T4P). Single cells …

Combining high-resolution single cell tracking experiments with numerical simulations, we
show that starvation-induced fruiting body formation in Myxococcus xanthus is a phase …

The ability of cells to reorganize in response to external stimuli is important in areas ranging
from morphogenesis to tissue engineering. While nematic order is common in biological …

Collective motion of active matter is ubiquitously observed, ranging from propelled colloids
to flocks of bird, and often features the formation of complex structures composed of agents …

Active Brownian motion with intermittent direction reversals is common in bacteria like
Myxococcus xanthus and Pseudomonas putida. We show that, for such a motion in two …

We study the two-dimensional motion of an active Brownian particle of speed v0, with
intermittent directional reversals in the presence of a harmonic trap of strength μ. The …

Motivated by various recent experimental findings, we propose a dynamical model of
intermittently self-propelled particles: active particles that recurrently switch between two …

We study self-propelled particles with velocity reversal interacting by uniaxial (nematic)
alignment within a coarse-grained hydrodynamic theory. Combining analytical and …
