Mechanical Theory of Nonequilibrium Coexistence and Motility-Induced Phase Separation
Ahmad K. Omar, Hyeongjoo Row, Stewart A. Mallory +1
Nonequilibrium phase transitions are routinely observed in both natural and synthetic systems. The ubiquity of these transitions highlights the conspicuous absence of a general the…
Confined active matter in external fields
Vaseem A. Shaik, Zhiwei Peng, John F. Brady +1
We analyze a dilute suspension of active particles confined between walls and subjected to fields that can modulate particle speed as well as orientation. Generally, the particle d…
Trapped-particle microrheology of active suspensions
Zhiwei Peng, John F. Brady
In microrheology, the local rheological properties such as viscoelasticity of a complex fluid are inferred from the free or forced motion of embedded colloidal probe particles. The…
Forced microrheology of active colloids
Zhiwei Peng, John F. Brady
Particle-tracking microrheology of dilute active (self-propelled) colloidal suspensions is studied by considering the external force required to maintain the steady motion of an im…
