Spacelike deformations: Higher-spin fields from scalar fields

Vincenzo Morinelli, Karl-Henning Rehren
May 21, 2019
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.
