Abstract |
|
Under certain hypotheses of smallness on the regular potential , we prove that the Dirac operator in , coupled with a suitable rescaling of , converges in the strong resolvent sense to the Hamiltonian coupled with a -shell potential supported on , a bounded surface. Nevertheless, the coupling constant depends nonlinearly on the potential ; Klein’s paradox comes into play. |
