Non-self-adjoint relativistic point interaction in one dimension
Lukáš Heriban, Matěj Tušek
The one-dimensional Dirac operator with a singular interaction term which is formally given by , where is an arbitrary matrix and $δ…
Spectral transition for Dirac operators with electrostatic -shell potentials supported on the straight line
Jussi Behrndt, Markus Holzmann, Matěj Tušek
In this note the two dimensional Dirac operator with an electrostatic -shell interaction of strength supported on a straight line is studied. We observe a…
On the Spectrum of a Quantum Dot with Impurity in the Lobachevsky Plane
P. Stovicek, M. Tusek
A model of a quantum dot with impurity in the Lobachevsky plane is considered. Relying on explicit formulae for the Green function and the Krein function which have been derive…
On the harmonic oscillator on the Lobachevsky plane
P. Stovicek, M. Tusek
We introduce the harmonic oscillator on the Lobachevsky plane with the aid of the potential where is the curvature radius and is the geodesic d…
