The Dirac propagator in the extreme Kerr metric
D. Batic, H. Schmid
Starting with the Dirac equation in the extreme Kerr metric we derive an integral representation for the propagator of solutions of the Cauchy problem with initial data in the clas…
Heun equation, Teukolsky equation, and type-D metrics
D. Batic, H. Schmid
Starting with the whole class of type-D vacuum backgrounds with cosmological constant we show that the separated Teukolsky equation for zero rest-mass fields with spin (g…
The generalized Heun equation in QFT in curved space-times
Davide Batic, Harald Schmid, Monika Winklmeier
In this article we give a brief outline of the applications of the generalized Heun equation (GHE) in the context of Quantum Field Theory in curved space-times. In particular, we r…
The Dirac propagator in the Kerr-Newman metric
D. Batic, H. Schmid
We give an alternative proof of the completeness of the Chandrasekhar ansatz for the Dirac equation in the Kerr-Newman metric. Based on this, we derive an integral representation f…
Chandrasekhar separation ansatz and the generalized total angular momentum for the Dirac equation in the Kerr-Newman metric
D. Batic, H. Schmid
In this paper we compute the square root of the generalized squared total angular momentum operator for a Dirac particle in the Kerr-Newman metric. The separation constant …
