Fully developed active turbulence defined through a non-equilibrium phase transition
Lasse Bonn, Tianxiang Ma, Olga Bantysh +7
Non-equilibrium systems challenge the standard definitions of phases and phase transitions from equilibrium statistical physics. For example, in active fluids continuous energy inj…
Topological Mixing and Braiding Universality in Polar Active Matter
Wei Feng, Tianyu Ren, Zhihan Ye +2
Connecting the autonomous kinematics of active matter to its emergent macroscopic transport is constrained by the requirement for high-resolution Eulerian velocity fields. Here, we…
Edge slip stabilizes confined active vortices by suppressing localized instabilities
Zhihan Ye, Tianyu Ren, Hao Luo +2
Confined active systems can sustain persistent vortical flows whose stability is strongly influenced by boundary conditions. At the individual level, active units generate internal…
Shear-Induced Wobbling and Motility Suppression in Swimming Bacteria
Wei Feng, Fanglong Dang, Hao Luo +3
The intricate wobbling motion of flagellated bacteria, characterized by the periodic precession of the cell body, is a determinant factor in their motility and navigation within co…
Bacterial swimming and accumulation on endothelial cell surfaces
Xin-Xin Xu, Yangguang Tian, Yuhe Pu +5
Flagellar-driven locomotion plays a critical role in bacterial attachment and colonization of surfaces, contributing to the risks of contamination and infection. Tremendous attempt…
