Finding normally hyperbolic invariant manifolds in two and three degrees of freedom with Hénon-Heiles-type potential

Abstract: We present the capability of Lagrangian descriptors for revealing the high dimensional phase space structures that are of interest in nonlinear Hamiltonian systems with index-1 saddle. These phase space structures include normally hyperbolic invariant manifolds (NHIM) and their stable and unstable manifolds, and act as codimenision-1 barriers to phase space transport. The method is applied to classical two and three degrees-of-freedom Hamiltonian systems which have implications for myriad applications in physi… Show more

“…The method was originally developed in the context of Lagrangian transport studies in fluid dynamics [30][31][32], but the wide applicability of the method has recently been recognized in chemistry [33][34][35][36][37][38][39][40][41]. The method is straightforward to implement computationally [42], the interpretation is clear, and it provides a "high resolution" method for exploring high-dimensional phase space with low-dimensional slices [43,44].…”

“…where the f i 's are the components of the velocity field f , and p ∈ (0, 1] and τ ∈ R + are two parameters. We focus on the definition (8) used in the literature [52,53], although other alternative definitions have been suggested. It is convenient to split Eq.…”

“…This leads to convergence within 3 steps in the sense of the trajectory returning to the initial condition. Once a small amplitude UPO is obtained, numerical continuation increases the amplitude and, correspondingly, the total energy, while a combination of bracketing and bisection method computes the UPO at the desired energy for a specified tolerance (Koon, Lo, Marsden, & Ross, 2011;Naik & Wiggins, 2019).…”
