Analysis of zero modes for Dirac operators with magnetic links

Fabian Portmann, Jeremy Sok, Jan Philip Solovej

In this paper we provide a means to approximate Dirac operators with magnetic fields supported on links in S3 (and R3) by Dirac operators with smooth magnet…

Spectral flow for Dirac operators with magnetic links

Fabian Portmann, Jérémy Sok, Jan Philip Solovej

This paper is devoted to the study of the spectral properties of Dirac operators on the three-sphere with singular magnetic fields supported on smooth, oriented links. As for Aharo…

Self-adjointness and spectral properties of Dirac operators with magnetic links

Fabian Portmann, Jérémy Sok, Jan Philip Solovej

We define Dirac operators on S3 (and R3) with magnetic fields supported on smooth, oriented links and prove self-adjointness of certain (natural) extensions…
