Standing-wave solutions in twisted multicore fibers

In the present work, we consider existence and spectral stability of standing wave solutions to a model for light propagation in twisted multi-core fiber with no gain or loss energy. Numerical parameter continuation experiments demonstrate sufficiently small values coupling parameter. Furthermore, waves exhibiting optical Aharonov-Bohm suppression, where there is single waveguide which remains unexcited, exist when twist $\phi$ number waveguides $N$ related by $\phi = \pi/N$. Spectral computations numerical timestepping simulations suggest that energy concentrated site are neutrally stable. Solutions asymmetric multi-pulse also briefly explored.
