标题： Dynamics of Excited BPS 3-Vortices

摘要： 我们分析了BPS 3旋涡解的动力学。 首先，对于未激发的旋涡，我们研究了具有$y \to -y$对称性的中心旋涡的二维模空间及其度量。 我们识别出描述等距共线和等边三角形构型正面对撞的一维子空间，其中测地线运动分别导致$90^\circ$和 60^\circ 散射。 其次，通过研究这些子空间上振动形状模态的频率谱，我们解释了如何通过形状模态激发将无力的测地线运动修改为混沌的多反弹碰撞模式。 显示英文摘要

摘要： We analyze the dynamics of BPS 3-vortex solutions. First, for unexcited vortices, we study the 2-dimensional moduli space of centred vortices with $y \to -y$ symmetry, and its metric. We identify the 1-dimensional subspaces describing the head-on collisions of equidistant collinear and equilateral triangle configurations, where geodesic motion results in $90^\circ$ and 60^\circ$ scattering, respectively. Second, by studying the frequency spectrum of vibrational shape modes along these subspaces, we explain how the force-free, geodesic motion is modified by shape mode excitations into a pattern of chaotic multi-bounce collisions.
