Generalized continuity equations from two-field Schrödinger Lagrangians
Aris G. B. Spourdalakis, George Pappas, Christian V. Morfonios +3
A variational scheme for the derivation of generalized, symmetry-induced continuity equations for Hermitian and non-Hermitian quantum mechanical systems is developed. We introduce…

Non-local Lagrangians: a variational approach to non-local conservation laws for wave mechanics
A. G. B. Spourdalakis, G. Pappas, P. A. Kalozoumis +2
We introduce a class of non-local Lagrangians which allow for the variational derivation of non-local conser- vation laws in a self-consistent manner. The formalism developed here…
