Module 3
Symmetry and Conservation Laws
1
Symmetry Groups of Hamiltonians and Lagrangians
Identify the symmetry group of a physical system's Hamiltonian or Lagrangian.
2
Noether's Theorem: Symmetries and Conservation Laws
Derive conserved quantities from continuous symmetries using Noether's theorem.
3
Symmetry Selection Rules
Apply selection rules derived from discrete or continuous symmetries to constrain physical processes.
4
Symmetry Breaking: Ground State vs. Hamiltonian
Identify spontaneous symmetry breaking by analyzing the symmetries of the ground state versus the Hamiltonian.
5
Goldstone Modes: From Broken Symmetry to Observable Properties
Predict the existence and properties of Goldstone modes arising from broken continuous symmetries.
6
Symmetry in Integrals and Matrix Elements
Use symmetry arguments to simplify the evaluation of integrals or matrix elements.
