Inequivalent Goldstone hierarchies for spontaneously broken spacetime symmetries
Abstract The coset construction is a powerful tool for building theories that non-linearly realize symmetries. We show that when the symmetry group is not semisimple and includes spacetime symmetries, different parametrizations of the coset space can prefer different Goldstones as essential or iness...
