WebActivity as a means to switch the interaction between ±1/2 defects. Beyond the LC structure, activity also influences dynamics. In the absence of active stress ( c = 0 μm −2 ), defects of opposite charge experience an attractive interaction, as the elastic energy is reduced through annihilation of +1/2 and −1/2 defects ( Fig. 3A, top, and ...

WebFeb 25, 2024 · However, the full extent to which the dynamics of active liquid crystals can be prescribed through control of the boundaries remains an open question. For example, recent theoretical work suggests that circular confinement generates robust circular flows that are largely independent of the details of the director boundary conditions ( 21 ).

The two-dimensional limit is appropriate to describe the experiments by Sanchez et al.[], where the microtubule bundles confined to a water–oil interface form an effectively two-dimensional dense nematic suspension, but also of … WebA recent simulation study revealed that active rotation can induce phase separation in mixtures of counter-rotating particles in 2D. In contrast to that of linearly self-propelled particles, the phase separation of counter-rotating fluids is accompanied by steady convective flows that originate at the fluid–fluid interface. the pacemaker of the mammalian heart is
