On PT Symmetry Systems: Invariance, Conservation Laws, and Reductions

Journal of Applied Mathematics, 2014, vol. 2014, issue 1

Abstract: An analysis of a PT symmetric coupler with “gain in one waveguide and loss in another” is made; a transformation in the PT system and some assumptions results in a scalar cubic Schrödinger equation. We investigate the relationship between the conservation laws and Lie symmetries and investigate a Lagrangian, corresponding Noether symmetries, conserved vectors, and exact solutions via “double reductions.”
