Conformal symmetry of an extended Schrodinger equation and its relativistic origin

Abstract

In this paper two things are done. We first prove that an arbitrary power $p$ of the Schrodinger Lagrangian in arbitrary dimension always enjoys the non-relativistic conformal symmetry. The implementation of this symmetry on the dynamical field involves a phase term as well as a conformal factor that depends on the dimension and on the exponent. This non-relativistic conformal symmetry is shown to have its origin on the conformal isometry of the power $p$ of the Klein-Gordon Lagrangian in one higher dimension which is related to the phase of the complex scalar field.
