Superexponential amplification, power blowup, and solitons sustained by non-Hermitian gauge potentials
Dmitry A. Zezyulin, Yaroslav V. Kartashov, Vladimir V. Konotop
We introduce a continuous one-dimensional non-Hermitian matrix gauge potential and study its effect on dynamics of a two-component field. The model is emulated by a system of evane…

Metastable two-component solitons near an exceptional point
Dmitry A. Zezyulin, Yaroslav V. Kartashov, Vladimir V. Konotop
We consider a two-dimensional nonlinear waveguide with distributed gain and losses. The optical potential describing the system consists of an unperturbed complex potential dependi…
