On Gait Stability: Correlations between Lyapunov Exponent and Stride Time Variability
Current Directions in Biomedical Engineering, 2022 Lyapunov exponent is a promising parameter to ascertain the stability of the human gait. In this work, we use a time-series model based on a second-order delay-system with inertial measurement units placed on the foot and wrist.

Probing phase transitions of regular black holes in anti-de Sitter space with Lyapunov exponent
European Physical Journal C: Particles and FieldsWe investigate the relationship between thermodynamic phase transitions and the Lyapunov exponent of charged regular anti-de Sitter black holes in quasi-topological gravity. Our results show that the Lyapunov exponent displays multivalued behavior during

Probing thermodynamic phase transitions of 4D R-charged black holes via lyapunov exponent
Nuclear Physics BWe investigate the thermodynamic phase structure of four-dimensional R-charged black holes–characterized by four independent U(1) charges–through the lens of Lyapunov exponents associated with unstable circular orbits of both massless and massive ...

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation
Advanced Intelligent Systems, EarlyView.Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

Probing the thermodynamics of charged Gauss Bonnet AdS black holes with the Lyapunov exponent
European Physical Journal C: Particles and FieldsIn this paper, we investigate the thermodynamic properties of the charged AdS Gauss–Bonnet black holes and their associations with the Lyapunov exponent. The chaotic features of the black holes and the isobaric heat capacity characterized by the Lyapunov

COVARIANT LYAPUNOV EXPONENTS FOR THE MIXMASTER [PDF]
The Tenth Marcel Grossmann Meeting, 2006 The dynamics of the Mixmaster Universe is analized in a covariant picture via Misner--Chitre-like variables for an ADM Hamiltonian approach. The system outcomes as isomorphic to a billiard on the Lobachevsky plane and Lyapunov exponents are calculated explicitly.

Synchronization and chaos in spin torque oscillator with two free layers
AIP Advances, 2020 The magnetization dynamics in a spin torque oscillator (STO) consisting of two in-plane magnetized free layers is studied by solving the Landau-Lifshitz-Gilbert equation and evaluating the Lyapunov exponent numerically.

Lyapunov Exponent Enhancement in Chaotic Maps with Uniform Distribution Modulo One Transformation
Chaos Theory and Applications, 2022 Most of the chaotic maps are not suitable for chaos-based cryptosystems due to their narrow chaotic parameter range and lacking of strong unpredictability.
