Non-local relativistic -shell interactions
Lukáš Heriban, Matěj Tušek
In this paper, new self-adjoint realizations of the Dirac operator in dimension two and three are introduced. It is shown that they may be associated with the formal expression $\m…

Approximation of one-dimensional relativistic point interactions by regular potentials revised
Matěj Tušek
We show that the one-dimensional Dirac operator with quite general point interaction may be approximated in the norm resolvent sense by the Dirac operator with a scaled regular pot…
