In this paper, a new three-dimensional chaotic system is proposed for image encryption. The
core of the encryption algorithm is the combination of chaotic system and compressed …

A bstract We introduce a simple quantum generalization of the spectrum of classical
Lyapunov exponents. We apply it to the SYK and XXZ models, and study the Lyapunov …

The out-of-time-ordered correlator has been proposed as an indicator of chaos in quantum
systems due to its simple interpretation in the semiclassical limit. In particular, its rate of …

Thermalisation in closed quantum systems occurs through a process of dephasing due to
parts of the system outside of the window of observation, gradually revealing the underlying …

In this paper, we give a general review on the application of ergodic theory to the
investigation of dynamics of the Yang–Mills gauge fields and of the gravitational systems, as …

In this work, our prime focus is to study the one to one correspondence between the
conduction phenomena in electrical wires with impurity and the scattering events …

In this paper we test for nonlinearity and chaos in some cryptocurrencies returns and
volatility. Financial markets are characterized by the so-called chaos model-data paradox …

Abstract Systems where time evolution follows a multiplicative process are ubiquitous in
physics. We study a toy model for such systems where each time step is given by …

In this study, we investigate the influence of the angular momentum of a charged particle
around Kerr-Newman-Taub-NUT black holes on the Lyapunov exponent and find spatial …

A bstract In this paper we provide a universal description of the behavior of the basic
operators of the Schwarzian theory in pure states. When the pure states are energy …
