Recent decades have seen a rise in the use of physics methods to study different societal
phenomena. This development has been due to physicists venturing outside of their …

Multifractality is ubiquitously observed in complex natural and socioeconomic systems.
Multifractal analysis provides powerful tools to understand the complex nonlinear nature of …

The free-energy principle (FEP) is a formal model of neuronal processes that is widely
recognised in neuroscience as a unifying theory of the brain and biobehaviour. More …

Serration and noise behaviors in plastically deforming solids are related to avalanches of
deformation processes. In the stress-strain curves, the serration characteristics are visible as …

We present a set of stylized empirical facts emerging from the statistical analysis of price
variations in various types of financial markets. We first discuss some general issues …

This book concerns the use of concepts from statistical physics in the description of financial
systems. The authors illustrate the scaling concepts used in probability theory, critical …

Fish travel in schools, birds migrate in flocks, honeybees swarm, and ants build trails. How
and why do these collective behaviors occur? Exploring how coordinated group patterns …

I find a hierarchical arrangement of stocks traded in a financial market by investigating the
daily time series of the logarithm of stock price. The topological space is a subdominant …

Since the subject of traffic dynamics has captured the interest of physicists, many surprising
effects have been revealed and explained. Some of the questions now understood are the …

Much has been learned, and even more needs to be learned, about designing organizations
and institutions. Since the 1960s this research has evolved from contingency to …
