论文摘要
我们通过数值和分析研究流体动力学对$ p-$ aTIC液晶中拓扑缺陷的动力学的影响，即具有$ p-$折叠旋转对称性的二维液晶。重要的是，我们发现流体力学为绕组数字缺陷$ s =（p-1）/p $和任意$ p $的缺陷提供了一种通用的被动自我推测机制。令人惊讶的是，我们发现流体动力学总是加速$ \ pm 1/p $缺陷对的an灭动态，与期望相反，这种效果随$ p $而增加。我们的字母铺平了理解细胞插入和上皮层中其他重塑事件的道路。
We investigate numerically and analytically the effects of hydrodynamics on the dynamics of topological defects in $p-$atic liquid crystals, i.e. two-dimensional liquid crystals with $p-$fold rotational symmetry. Importantly, we find that hydrodynamics fuels a generic passive self-propulsion mechanism for defects of winding number $s=(p-1)/p$ and arbitrary $p$. Strikingly, we discover that hydrodynamics always accelerates the annihilation dynamics of pairs of $\pm 1/p$ defects, and that, contrary to expectations, this effect increases with $p$. Our Letter paves the way towards understanding cell intercalation and other remodelling events in epithelial layers.
