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 …

Modern financial markets are characterized by a rapid flow of information, a vast number of
participants having diversified investment horizons, and multiple feedback mechanisms …

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

This paper investigates the volatility processes of stablecoins and their potential stochastic

Many of the insights of economics seem to be qualitative, with many fewer reliable
quantitative laws. However a series of power laws in economics do count as true and …

A power law (PL) is the form taken by a large number of surprising empirical regularities in

nonlinearly interacting elements. These systems are open, they interchange information or …

This paper analyzes the stability of stablecoins and proposes a framework to test for
absolute and relative stability of stablecoins. Based on high-frequency data, we find strong …

Insights into the dynamics of a complex system are often gained by focusing on large
fluctuations. For the financial system, huge databases now exist that facilitate the analysis of …

We analyze cross correlations between price fluctuations of different stocks using methods
of random matrix theory (RMT). Using two large databases, we calculate cross-correlation …
