Galilean symmetry in generalized abelian Schrödinger-Higgs models with and without gauge field interaction
arXiv:1503.04844 · doi:10.1142/S0217732315502119
Abstract
We consider a generalization of nonrelativistic Schrödinger-Higgs Lagrangian by introducing a nonstandard kinetic term. We show that this model is Galilean invariant, we construct the conserved charges associated to the symmetries and realize the algebra of the Galilean group. In addition, we study the model in the presence of a gauge field. We also show that the gauged model is Galilean invariant. Finally, we explore relations between twin models and their solutions.
