SYQC: Symposium Topology in Quantum and Classical Physics – From Topological Insulators to Active Matter

SYQC 1: Topology in Quantum and Classical Physics – From Topological Insulators to Active Matter

Wednesday, March 29, 2023, 15:00–17:45, HSZ 01

The field of solid state physics, especially of material physics, has grown vigorously thanks to the discovery of topological protection and the universality of topological notions in many solid state systems. These ideas, rooted in the low temperature physics, have since expanded into other domains of physics, even into bio- and geophysics. The topological defects in bacterial colonies and tissues decide the life and death of cells; topological modes arise in active matter on curved surfaces; equatorial waves form at the boundary between two regions with opposite sign of the Coriolis force. It is fascinating that topological ideas flourish even in the chaotic environments of living matter and Earth systems. The aim of this symposium is to bring together the speakers and audience from the seemingly disparate fields of biological and low temperature physics, to explore together the mathematical connection between these two domains.
