  • Computational Method for Phase Space Transport with Applications to Lobe Dynamics and Rate of Escape
    Computational Method for Phase Space Transport with Applications to Lobe Dynamics and Rate of Escape Shibabrat Naik1, Francois Lekien2, and Shane D. Ross3 1,3Engineering Mechanics Program, Department of Biomedical Engineering & Mechanics, Virginia Tech, Blacksburg, VA-24061, USA 2Ecole´ Polytechnique, Universite´ Libre de Bruxelles, B-1050 Brussels, Belgium Abstract Lobe dynamics and escape from a potential well are general frameworks introduced to study phase space transport in chaotic dynamical systems. While the former approach studies how regions of phase space are transported by reducing the flow to a two-dimensional map, the latter approach studies the phase space structures that lead to critical events by crossing periodic orbit around saddles. Both of these frameworks require computation with curves represented by millions of points—computing intersection points between these curves and area bounded by the segments of these curves—for quantifying the transport and escape rate. We present a theory for computing these intersection points and the area bounded between the segments of these curves based on a classification of the intersection points using equivalence class. We also present an alternate theory for curves with nontransverse intersections and a method to increase the density of points on the curves for locating the intersection points accurately. The numerical implementation of the theory presented herein is available as an open source software called Lober. We used this package to demonstrate the application of the theory

  • Revealing the Phase Space Structure of Hamiltonian Systems Using the Action
    Revealing the phase space structure of Hamiltonian systems using the action Francisco Gonzalez Montoya, Makrina Agaoglou, and Matthaios Katsanikas School of Mathematics, University of Bristol, Fry Building, Woodland Road, Bristol, BS8 1UG, United Kingdom. Abstract In this work, we analyse the properties of the Maupertuis' action as a tool to reveal the phase space structure for Hamiltonian systems. We construct a scalar field with the action's values along the trajectories in the phase space. The different behaviour of the trajectories around important phase space objects like unstable periodic orbits, their stable and unstable manifolds, and KAM islands generate characteristic patterns on the scalar field constructed with the action. Using these different patterns is possible to identify the skeleton of the phase space and understand the dynamics. Also, we present a simple argument based on the conservation of the energy and the behaviour of the trajectories to understand the values of their actions. In order to show how this tool reveals the phase space structures and its effectiveness, we compare the scalar field constructed with the actions with Poincare maps for the same set of initial conditions in the phase space of an open Hamiltonian system with 2 degrees of freedom. The study of phase space structure is a fundamental problem in dynamical systems. It is essential to understand the trajectories' behaviour and properties from a theoretical and practical perspective. The traditional tools to visualise the phase space structure like the projection of the trajectories in a plane or Poincare maps are important tools to understand many properties of ODE systems' phase space with 3 dimensions.

    Support vector machines for learning reactive islands Shibabrat Naik,a) Vladim´ır Krajˇn´ak,b) and Stephen Wigginsc) School of Mathematics, University of Bristol Fry building, Woodland Road, Bristol BS8 1UG, United Kingdom (Dated: 20 July 2021) We develop a machine learning framework that can be applied to data sets derived from the trajectories of Hamilton's equations. The goal is to learn the phase space structures that play the governing role for phase space transport relevant to particu- lar applications. Our focus is on learning reactive islands in two degrees-of-freedom Hamiltonian systems. Reactive islands are constructed from the stable and unsta- ble manifolds of unstable periodic orbits and play the role of quantifying transition dynamics. We show that support vector machines (SVM) is an appropriate machine learning framework for this purpose as it provides an approach for finding the bound- aries between qualitatively distinct dynamical behaviors, which is in the spirit of the phase space transport framework. We show how our method allows us to find re- active islands directly in the sense that we do not have to first compute unstable periodic orbits and their stable and unstable manifolds. We apply our approach to the H´enon-HeilesHamiltonian system, which is a benchmark system in the dynamical systems community. We discuss different sampling and learning approaches and their advantages and disadvantages. arXiv:2107.08429v1 [math.DS] 18 Jul 2021 a)Corresponding author: [email protected] b)[email protected] c)[email protected] 1 Prediction and control of transition between potential wells across index-one saddles are of importance in a diverse array of non-linear systems in physics, chemistry, and engineering.

  • Strong Flows of Dilute Suspensions of Microstructure Andrew J
    Strong flows of dilute suspensions of microstructure Andrew J. Szeri* Department of MechanicaI and Environmentat Engineering, University of California, Santa Barbara, Calljrrnia 93 IO6 Stephen Wiggins Applied Mechanics, California Institute of Technology, Pasadena, Cal@rnia 91125 and Center for Nonlinear Studies, Los Alamos National Laboratory, Las Alamos, New Mexico 87545 L. Gary Lea1 Department of Chemical and Nuclear Engineering, University of California, Santa Barbara, California 93106 (Received 28 August 1990) We consider dilute suspensions that have a microstructure that may be characterized by an axial state vector. Examples include axisymmetric particles, line elements of the fluid itself, or, as an approximation, droplets of fluid or polymer molecules. Past studies, in which sufficient conditions for stretch or coherent orientation of the microstructure are obtained for steady flows with homogeneous velocity gradient. tensors are shown not to apply to the general situation. Instead, a careful analysis of the microdynamical equations reveals that stretching and orientation of the microstructure by the flow must be analyzed over a time interval. Using techniques from the theory of dynamical systems, a quantitative measure is developed to determine orientations and/or stretched lengths of the microstructure, that are robust and attractive to nearby states. This leads to a strongJlow criterion for unsteady flows with inhomogeneous velocity gradient tensors in which the effects of history dependence are apparent. A particular model system is treated in the case of general two-dimensional flow. The sensitivity of the results to changes in the modeling assumptions is investigated. 1438 Phys.

These phase space structures are an integral part of understanding the reaction mechanism, that is the path- ways that reactive trajectories undertake, in the presence of a solvent. Our approach involves detecting the analogs of the reactive islands first discussed in the works by Davis, Marston, De Leon, Berne and coauthors 1–4 in the system-bath model using Lagrangian descriptors. We first present the structure of the reactive islands for the two degrees of freedom system modelling isomerization in the absence of the bath using direct computation of cylindrical (tube) manifolds and verify the Lagrangian descriptor method for detecting the reactive islands. The hierarchy of the reactive islands as indicated in the recent work by Patra and Keshavamurthy 5 is shown to be related to the temporal features in committor probabilities. Next, we investigate the influence of the solvent on the reactive islands that we previously revealed for the two degrees of freedom system and discuss the use of the Lagrangian descriptor in the high-dimensional phase space of the system-bath model.

The model is a two mode truncation of the Euler-Bernoulli beam equation subject to compressive stress applied at both ends. We consider parameter regimes where the first mode is unstable and the second mode can be either stable or unstable, and the remaining modes (neglected) are always stable. Material parameters used correspond to a silicon nanobeam. The two mode model Hamiltonian is the sum of a (diagonal) kinetic energy term and a potential energy term. The form of the potential energy function suggests an analogy with isomerisation reactions in chemistry, where ‘isomerisation’ here corresponds to a transition between two stable beam configurations. We therefore study the dynamics of the buckled beam using the conceptual framework established for the theory of isomerisation reactions. When the second mode is stable the potential energy surface has an index one saddle and when the second mode is unstable the potential energy surface has an index two saddle and two index one saddles. Symmetry of the system allows us to readily construct a phase space dividing surface between the two “isomers” (buckled states); we rigorously prove that, in a specific energy range, it is a normally hyperbolic invariant manifold.
