Essential self-adjointness of symmetric first-order differential systems and confinement of Dirac particles on bounded domains in ${\mathbb{R}}^d$

Gheorghe Nenciu, Irina Nenciu, Ryan Obermeyer

We prove essential self-adjointness of Dirac operators with Lorentz scalar potentials which grow sufficiently fast near the boundary $\partial \Omega$ of the spatial domain $Ω\subset\mat…
