Hamiltonian Flow is a Canonical Transformation | Strange Non-Intuitive Momenta | Lecture 8

Lecture 8, course on Hamiltonian and nonlinear dynamics. Symplecticness of vector field and flow map for Hamilton's canonical equations of motion. Infinitesimally symplectic matrix. Example systems, showing that their flow map satisfies the condition of a canonical transformation. Strange momentum definitions, that is, generalized momentum vs mechanical momentum. Examples: charged particle in electromagnetic fields, motion viewed in a rotating frame: circular restricted 3-body problem; and a particle in linear restoring force and nonlinear term. ► Next: Hamilton-Jacobi Theory | Finding the Best Canonical Transformation | Examples    • Hamilton-Jacobi Theory | Canonical Transfo...   ► Previous, Generating Function of a Canonical Transformation | Examples and the Big Picture    • Generating Function of a Canonical Transfo...   ► Dr. Shane Ross, Virginia Tech professor (Caltech PhD) Instructor intro    • Professor Shane Ross Introduction   ► New lectures posted regularly Subscribe https://is.gd/RossLabSubscribe​ ► Follow me on Twitter   / rossdynamicslab   Chapters 0:00 Strange momentum definitions 22:00 Flow of Hamilton's Equations is a Canonical Transformation 30:48 Conditions on eigenspectrum for equilibrium points 45:27 Example Hamiltonian flow maps ► Class notes in PDF form https://is.gd/AdvancedDynamicsNotes ► in OneNote form https://1drv.ms/u/s!ApKh50Sn6rEDiRgCY... ► See the entire playlist for this online course: Advanced Dynamics - Hamiltonian Systems and Nonlinear Dynamics https://is.gd/AdvancedDynamics This course gives the student advanced theoretical and semi-analytical tools for analysis of dynamical systems, particularly mechanical systems (e.g., particles, rigid bodies, continuum systems). We discuss methods for writing equations of motion and the mathematical structure they represent at a more sophisticated level than previous engineering dynamics courses. We consider the sets of possible motion of mechanical systems (trajectories in phase space), which leads to topics of Hamiltonian systems (canonical and non-canonical), nonlinear dynamics, periodic & quasi-periodic orbits, driven nonlinear oscillators, resonance, stability / instability, invariant manifolds, energy surfaces, chaos, Poisson brackets, basins of attraction, etc. ► This course builds on prior knowledge of Lagrangian systems, which have their own lecture series, 'Analytical Dynamics' https://is.gd/AnalyticalDynamics ► Continuation of this course on a related topic Center manifolds, normal forms, and bifurcations https://is.gd/CenterManifolds ► A simple introductory course on Nonlinear Dynamics and Chaos https://is.gd/NonlinearDynamics ► References The class will largely be based on the instructor’s notes.
