Generation of gravitational waves in dynamical Chern-Simons gravity
Zhi-Zhang Peng, Zhen-Min Zeng, Chengjie Fu +1
We investigate gravitational waves (GWs) generated in a two-field inflationary model with a non-canonical kinetic term, in which the gravitational Chern-Simons term is coupled to a…
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…
