Strain Waves Generate Compression and Trigger Buckling in Active Polymers
Wen-de Tian, Kang Chen, Tianhui Zhang
Chemical reactions can sustain polymer motion without necessarily generating the compression required for buckling. Theory and simulations show that tension-dependent chemical tran…
Complex pattern in periodically driven binary Quincke colloids
Chuan Yu Zhang, Mu Yue Zhao, Xiao Yi Zhou +3
Binary active systems offer a minimal platform for understanding how component heterogeneity organizes non-equilibrium structures. Here we show that in a binary Quincke system driv…
Spontaneous Motion Generates Reversible Nonreciprocity in an Achiral Active Elastic Ring
Wen-de Tian, Kang Chen, Tianhui Zhang
Nonreciprocal mechanical response is usually associated with built-in directional couplings, structural chirality, or external driving. Whether an achiral active body can instead g…
Desorption of an active Brownian polymer from a homogeneous attractive surface
Guo-qiang Feng, Wen-de Tian
The interfacial behavior of active Brownian polymer (ABPO) is studied by Langevin dynamics simulations. On the dependence of adsorption strength and activity characterized by Pecle…
An active filament on a cylindrical surface: morphologies and dynamics
Chen Shen, Chao-ran Qin, Tian-liang Xu +2
Structure and dynamics of an active polymer on a smooth cylindrical surface are studied by Brownian dynamics simulations. The effect of active force on the polymer adsorption behav…
Escape of an Active Ring from an Attractive Surface: Behaving Like a Self-Propelled Brownian Particle
Bin Tang, Jin-cheng Gao, Kang Chen +2
Escape of active agents from metastable states is of great interest in statistical and biological physics. In this study, we investigate the escape of a flexible active ring, compo…
Constrained motion of self-propelling eccentric disks linked by a spring
Tian-liang Xu, Chao-ran Qin, Bin Tang +5
It has been supposed that the interplay of elasticity and activity plays a key role in triggering the non-equilibrium behaviors in biological systems. However, the experimental mod…
