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 ...

Stability Analysis of Switched Linear Singular Systems with Unstable and Stable Modes
Entropy, 2023 In this paper, stability is studied for a class of switched singular systems containing both stable and unstable modes. By introducing a time-varying piecewise Lyapunov function (TVPLF) and a mode-dependent average dwell time (ADT) switching rule, the ...

Lyapunov spectra and conjugate-pairing rule for confined atomic fluids [PDF]
The 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.

Stability of quantum motion: Beyond Fermi-golden-rule and Lyapunov decay [PDF]
Physical Review E, 2004 We study, analytically and numerically, the stability of quantum motion for a classically chaotic system. We show the existence of different regimes of fidelity decay which deviate from Fermi Golden rule and Lyapunov decay.

Ruling Out Positive Lyapunov Exponents by Using the Jacobian’s Second Additive Compound Matrix
IEEE Control Systems Letters, 2022 Second additive compound matrices of the system’s Jacobian are used to formulate sufficient conditions to rule out existence of attractors with positive Lyapunov exponents. The criteria are expressed in terms of Lyapunov dissipation inequalities or Linear Matrix Inequalities amenable to analytic verification.
