Shell interactions for Dirac operators: On the point spectrum and the confinement

Spectral properties and the confinement phenomenon for the coupling $H + V$ are studied, where $H =-i\alpha \cdot \nabla + m\beta$ is the free Dirac operator in $\mathbb{R}^3$ and $V$ is a measure-valued potential. The potentials V under consideration are given in terms of surface measures on the bo...
