The functional squeeze operator algebra in Maxwell–Chern–Simons electrodynamics

Using annihilation and creation squeeze operators, we construct a basis of Hermitian generators obeying the $SU(2)$ Lie algebra. We discuss the relations between the Maxwell–Chern–Simons electrodynamics vacuum and the normal vacuum and show that the most general Bogoliubov transformation is just a functional rotation in the Fock space.
