Congruence of Dirac operators with applications to generalized MIT bag models

Joaquim Duran, Konstantin Pankrashkin

The paper introduces a simple congruence transformation that shifts coupling parameters for Dirac operators with shell interactions, and uses it to derive new results on the self‑a…
