Spectral transition for Dirac operators with electrostatic $\delta$-shell potentials supported on the straight line

Jussi Behrndt, Markus Holzmann, Matěj Tušek

In this note the two dimensional Dirac operator $A_{\eta }$ with an electrostatic $\delta$-shell interaction of strength $\eta \in \mathbb{R}$ supported on a straight line is studied. We observe a…
