Approximation of Dirac operators with $I^´$ -shell potentials in the norm resolvent sense, II. Quantitative results

Jussi Behrndt, Markus Holzmann, Christian Stelzer-Landauer

This paper is devoted to the approximation of two and three-dimensional Dirac operators $H_{V I^´_{I^} £}$ with combinations of electrostatic and Lorentz scalar $I^´$ -shell i…

Approximation of Dirac operators with confining electrostatic and Lorentz scalar $I^´$ -shell potentials

Christian Stelzer-Landauer

In this paper we study the approximation of Dirac operators with $I^´$ -shell potentials in the norm resolvent sense. In particular, we consider the approximation of Dirac operators…

Two-dimensional SchrÃ¶dinger operators with non-local singular potentials

LukÃ¡Å¡ Heriban, Markus Holzmann, Christian Stelzer-Landauer +2

In this paper we introduce and study a family of self-adjoint realizations of the Laplacian in $L^{2} (R^{2})$ with a new type of transmission conditions along a closed bi-Lips…

Nonrelativistic Limit of Generalized MIT Bag Models and Spectral Inequalities

Jussi Behrndt, Dale Frymark, Markus Holzmann +1

For a family of self-adjoint Dirac operators $- i c (I^\pm \cdot \nabla) + \frac{c ^{2}}{2}$ subject to generalized MIT bag boundary conditions on domains in $R^{3}$ it is shown that…
