活性固体和活性晶体中弹性驱动的集体运动

Elasticity-driven collective motion in active solids and active crystals

Eliseo Ferrante, Ali Emre Turgut, Marco Dorigo, Cristián Huepe

摘要:

我们介绍了一个简单的模型,自推进剂连接线性弹簧,没有明确的对齐规则。在临界噪声水平以下,代理自组织成一个集体平移或旋转组。我们推导了弹性薄板近似下平移态的解析稳定性条件。我们提出了一种基于弹性的机制,通过将自推进能量级联到低能模式来驱动收敛到集体运动。鉴于其简单性和普遍性,这种机制可以在各种生物和机器人群体中发挥相关作用。

英文摘要:

We introduce a simple model of self-propelled agents connected by linear springs, with no explicit alignment rules. Below a critical noise level, the agents self-organize into a collectively translating or rotating group. We derive analytical stability conditions for the translating state in an elastic sheet approximation. We propose an elasticity-based mechanism that drives convergence to collective motion by cascading self-propulsion energy towards lower-energy modes. Given its simplicity and ubiquity, such mechanism could play a relevant role in various biological and robotic swarms.
