Hadamard states on spherically symmetric characteristic surfaces, the semi-classical Einstein equations and the Hawking effect
Daan W. Janssen, Rainer Verch
We investigate quasi-free Hadamard states defined via characteristic initial data on null cones centred at the axis of symmetry in spherically symmetric space-times. We characteriz…

Quantum fields on semi-globally hyperbolic space-times
Daan Willem Janssen
We introduce a class of space-times modeling singular events such as evaporating black holes and topology changes, which we dub as semi-globally hyperbolic space-times. On these sp…
