Integer Topological Defects Reveal Anti-Symmetric Forces in Active Nematics
Zihui Zhao, Yisong Yao, He Li +5
Cell layers are often categorized as contractile or extensile active nematics but recent experiments on neural progenitor cells with induced topological defects challenge this…

Active particles in a tube: a generalized entropy potential approach
Yongfeng Zhao
We study the transport of self-propelled noninteracting active Brownian particles (ABPs) and run-and-tumble particles (RTPs) in long tubes of varying widths. Using a moment expansi…

Active Young-Dupré Equation: How Self-organized Currents Stabilize Partial Wetting
Yongfeng Zhao, Ruben Zakine, Adrian Daerr +3
The Young-Dupré equation is a cornerstone of the equilibrium theory of capillary and wetting phenomena. In the biological world, interfacial phenomena are ubiquitous, from the spr…
