- Recipe for quantization
- Construct the Lagrangian by inspection
- Differentiate the Lagragian to find the conjugate variables
- Use the conjugate variables to perform a Legendre transformation from the Lagrangian to the Hamiltonian
- The quantization of the wave equation is discussed in appendix C of Kittel and the quantization of electrons in a magnetic field is discussed in Appendix G of Kittel.
