- Schwinger's principle and gauge fixing in the free electromagnetic field
- Universidade Estadual Paulista (UNESP)
- 1594-9982
- A manifestly covariant treatment of the free quantum eletromagnetic field, in a linear covariant gauge, is implemented employing Schwinger's variational principle and the B-field formalism. It is also discussed the Abelian Proca model as an example of a system without constraints. © Società Italiana di Fisica.
