Quantum Bounds on the Generalized Lyapunov Exponents [PDF]

Entropy, 2023
We discuss the generalized quantum Lyapunov exponents Lq, defined from the growth rate of the powers of the square commutator. They may be related to an appropriately defined thermodynamic limit of the spectrum of the commutator, which plays the role of ...

Recurrence and Lyapunov Exponents [PDF]

Moscow Mathematical Journal, 2003
We prove two inequalities between the Lyapunov exponents of a diffeomorphism and its local recurrence properties. We give examples showing that each of the inequalities is optimal.

Probing phase structure of black holes with Lyapunov exponents

Journal of High Energy Physics, 2022
We conjecture that there exists a relationship between Lyapunov exponents and black hole phase transitions. To support our conjecture, Lyapunov exponents of the motion of particles and ring strings are calculated for Reissner-Nordström-AdS black holes ...

Tranquilizer effect on the Lyapunov exponents of lame horses [PDF]

Heliyon, 2020
Tranquilization of horses with acepromazine has been used to suppress erratic head movements and increase the accuracy of a lameness examination. Some equine clinicians believe that tranquilization with acepromazine will make lameness more evident by ...

EEG analysis in patients with schizophrenia based on Lyapunov exponents

Informatics in Medicine Unlocked, 2020
The present work focused on study of the chaotic nature of the electroencephalogram (EEG) signal in schizophrenia by assessing Lyapunov exponents, which can serve as indicators of specific brain function suffered from the disease.

Analysis of Pseudo-Lyapunov Exponents of Solar Convection Using State-of-the-Art Observations [PDF]

Entropy, 2021
The solar photosphere and the outer layer of the Sun’s interior are characterized by convective motions, which display a chaotic and turbulent character.

Lyapunov Exponents of a Discontinuous 4D Hyperchaotic System of Integer or Fractional Order [PDF]

Entropy, 2018
In this paper, the dynamics of local finite-time Lyapunov exponents of a 4D hyperchaotic system of integer or fractional order with a discontinuous right-hand side and as an initial value problem, are investigated graphically.

Lyapunov exponents as probes for a phase transition of a Kerr-AdS black hole

Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
In this letter, we study proper time Lyapunov exponents and coordinate time Lyapunov exponents of chaos for both massless and massive particles orbiting a four-dimensional Kerr-AdS black hole, and explore their relationships with the phase transition of ...
