In contrast to Hamiltonian perturbation theory that changes the time evolution, "spacelike deformations" proceed by changing the translations (momentum operators). The free Maxwell theory is the first member of an infinite family of spacelike deformations of the complex massless Klein-Gordon quantum field into fields of higher spin.
