Eigenvalues bifurcating from the continuum in two-dimensional potentials generating non-Hermitian gauge fields

D. I. Borisov, D. A. Zezyulin

It has been recently shown that complex two-dimensional (2D) potentials $V_{\epsilon }(x,y)=V(y+\mathrm{i}\epsilon \eta (x))$ can be used to emulate non-Hermitian matrix gauge fields…
