Abstract

Cell motility is connected to the spontaneous symmetry breaking of a circular shape. In https://doi.org/10.1103/PhysRevLett.110.078102, Blanch-Mercader and Casademunt perfomed a nonlinear analysis of the minimal model proposed by Callan and Jones https://doi.org/10.1103/PhysRevLett.100.258106 and numerically conjectured the existence of traveling solutions once that symmetry is broken. In this work, we prove analytically that conjecture by means of nonlinear bifurcation techniques.

自发对称破缺下肌动蛋白片段的移动性
细胞运动与圆形的自发对称破缺有关。在 https://doi.org/10.1103/PhysRevLett.110.078102,Blanch-Mercader 和 Casademunt 对 Callan 和 Jones 提出的最小模型进行了非线性分析 https://doi.org/10.1103/PhysRevLett.100.258106,并从数值上猜想,一旦对称性被打破,就会存在行进解。在这项工作中,我们通过非线性分岔技术分析证明了这一猜想。
