 Course overview – short abstract

In this course, students become fluent in the use of advanced analytical methods of classical mechanics, mainly in the form of Lagrangian and Hamiltonian mechanics. While doing so, they are introduced to notions such as the analysis of phase-space dynamics, algebraic diagonalization and normal modes of vibrations, canonical transformations, constants of motion, Poisson brackets, action-angle variables, Hamilton-Jacoby theory, and the fundamental connection between symmetry and conservation laws.

Motion in a central potential in three dimensions; conservation of angular momentum; general solution; solution of the Kepler problem; scattering from a central potential, calculation of the differential cross section. (Chapters 3, 4 and 9 of H&F).

Chapter 3: Advanced Theory

Conservation laws and Noether’s theorem. Legendre transformation and Hamilton’s equations. Canonical transformations, generating functions,

Poisson brackets; Hamilton-Jacoby equation; action-angle variables in one dimension. (Chapters 5 and 6 of H&F).
