Congruence of Dirac operators with applications to generalized MIT bag models
Abstract
We highlight a simple congruence transform that shifts coupling parameters for Dirac operators with shell interactions. As one of the consequences, this leads to new observations concerning the self-adjointness and the infinite mass interpretation of generalized MIT bag models.
