Abstract | Defects are ubiquitous. Hence, many natural structures and patterns trace their origin to the defects present in the underlying media. Equilibrium defects and the associated patterns have been studied extensively in the last fifty years. Concurrently, the advent of the physics of living systems has established the presence of defects in many biological systems. By the nature of biological systems, these defects form out of thermal equilibrium. The behavior of nonequilibrium defects is spectacularly different from their equilibrium counterpart and leads to nontrivial spatiotemporal patterns. In this talk, I’ll show the origin and the behavior of some of these patterns and their biological relevance. |
