Lyapunov Spectra and Conjugate-Pairing Rule for Confined Atomic Fluids [PDF]
Journal of Chemical Physics, 2010 In this work we present nonequilibrium molecular dynamics simulation results for the Lyapunov spectra of atomic fluids confined in narrow channels of the order of a few atomic diameters. We show the effect that realistic walls have on the Lyapunov spectra. All the degrees of freedom of the confined system have been considered.

Turkish Journal of Engineering, 2021 Various system parameter variations occur during operations in several existing process industries. These parameter variations result in process shifts, thus, requiring adequate control strategies to compensate for these alterations, which consequently maintain desired system response.

Safe and adaptive control of non-stationary stochastic systems via Lyapunov-constrained distributional reinforcement learning [PDF]
Scientific ReportsNon-stationary environments pose significant challenges for reinforcement learning (RL), particularly in safety-critical applications like robotics and energy systems, where adaptability, stability, and robustness to uncertainty are essential. This paper

Physical Review Letters, 1997 for the exponents of systems with more than one pair of exponents. In this paper we present an analytical calculation of the four Lyapunov exponents for a dilute, three-dimensional Lorentz gas with randomly placed hard sphere scatterers, both for an equilibrium system and for a system where the moving particle is placed in a thermostatted applied field.

Observability of fidelity decay at the Lyapunov rate in few-qubit quantum simulations [PDF]
Quantum, 2022 In certain regimes, the fidelity of quantum states will decay at a rate set by the classical Lyapunov exponent. This serves both as one of the most important examples of the quantum-classical correspondence principle and as an accurate test for the ...
