Strong gravitational lensing of rotating regular black holes in non-minimally coupled Einstein-Yang-Mills theory
Ruanjing Zhang, Jiliang Jing, Zhipeng Peng +1
The strong gravitational lensing of a regular and rotating magnetic black hole in non-minimally coupled Einstein-Yang-Mills theory is studied. We find that, with the increase of an…
AI-aided Geometric Design of Anti-infection Catheters
Tingtao Zhou, Xuan Wan, Daniel Zhengyu Huang +6
Bacteria can swim upstream due to hydrodynamic interactions with the fluid flow in a narrow tube, and pose a clinical threat of urinary tract infection to patients implanted with c…
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…
Activity-induced propulsion of a vesicle
Zhiwei Peng, Tingtao Zhou, John F. Brady
Modern biomedical applications such as targeted drug delivery require a delivery system capable of enhanced transport beyond that of passive Brownian diffusion. In this work an osm…
Distribution and pressure of active Lévy swimmers under confinement
Tingtao Zhou, Zhiwei Peng, Mamikon Gulian +1
Many active matter systems are known to perform Lévy walks during migration or foraging. Such superdiffusive transport indicates long-range correlated dynamics. These behavior patt…
Propulsion via flexible flapping in granular media
Zhiwei Peng, Yang Ding, Kyle Pietrzyk +2
Biological locomotion in nature is often achieved by the interaction between a flexible body and its surrounding medium. The interaction of a flexible body with granular media is l…
Maximizing propulsive thrust of a driven filament at low Reynolds number via variable flexibility
Zhiwei Peng, Gwynn J. Elfring, On Shun Pak
At low Reynolds numbers the locomotive capability of a body can be dramatically hindered by the absence of inertia. In this work, we show how propulsive performance in this regime…
Characteristics of undulatory locomotion in granular media
Zhiwei Peng, On Shun Pak, Gwynn J. Elfring
Undulatory locomotion is ubiquitous in nature and observed in different media, from the swimming of flagellated microorganisms in biological fluids, to the slithering of snakes on…
