Non-Local Currents and the Structure of Eigenstates in Planar Discrete Systems with Local Symmetries
Malte Röntgen, Christian V. Morfonios, Fotios Diakonos +1
Local symmetries are spatial symmetries present in a subdomain of a complex system. By using and extending a framework of so-called non-local currents that has been established rec…
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…
Nonlocal discrete continuity and invariant currents in locally symmetric effective Schrödinger arrays
C. V. Morfonios, P. A. Kalozoumis, F. K. Diakonos +1
We develop a formalism relating nonlocal current continuity to spatial symmetries of subparts in discrete Schrödinger systems. Breaking of such local symmetries hereby generates so…
