　　 主讲人简介：

　　 Dr. Cristián Huepe is a physicist conducting research in complex systems, nonlinear dynamics and statistical physics. He has worked in various subjects throughout his career, including: superfluidity, Bose-Einstein condensates, a toy cosmology model, finite-time singularities, spatiotemporal chaos, defect dynamics, and Faraday waves. His current research focuses on the dynamics of collective motion and complex networks.

　　Dr. Huepe obtained his PhD in Physics at the école Normale Supérieure in Paris, after completing undergraduate studies in his native Chile. He then worked as a postdoc in Chicago, first at the University of Chicago and later at Northwestern University. Since 2006, Dr. Huepe has been working as an independent researcher supported by research grants from the US National Science Foundation, heading CHuepe Labs in Chicago. Dr. Huepe is also an Adjunct Research Professor at Northwestern University’s Department of Engineering Sciences and Applied Mathematics, External Faculty member at the Northwestern Institute on Complex Systems, and a regular visitor at the Max Planck Institute for the Physics of Complex Systems (Dresden, Germany). His work has been featured in Science Daily, Focus Online, National Geographic Germany and Wired Magazine, among others.

　　内容简介：

　　Self-organization is often observed in active matter systems such as cell colonies, developing tissue, insect swarms, bird flocks, and groups of autonomous robots.  Its emergence in fluid-like systems of self-propelled agents with aligning interactions has been the focus of intense research, and can be viewed as a decentralized consensus process on local heading directions. By contrast, collective motion that results from position-based springlike attraction-repulsion forces cannot be directly mapped to consensus processes and are much less understood. In this talk, I will present simple models of active self-organizing dynamics with springlike interactions and explore their characteristic features, including energy cascades, mode selection, long-range correlations and multi-scale self-organization, as well as their potential applications to artificial-life studies and control algorithms.
