Emergent phenomena in physics and econophysics — •Radin Dardashti — IZWT, Wuppertal, Germany

Various kinds of phenomena and properties in physics are regarded as emergent in some sense or another. The temperature of a system, critical exponents or the Hawking effect are all discussed in this context. However, there can be significant differences in their realizations and theoretical treatment, with important consequences for their interpretation. In the econophysical literature the stylized facts of economics are also understood as emerging out of the complex system. But how should we understand the emergence of stylized facts and what does this mean for the treatment of these models?

I will discuss examples of emergent phenomena from fundamental physics and embed it into a general framework, which allows us to shed light on these questions.
