The Unruh and Hawking effects are investigated on certain families of
topologically non-trivial spacetimes using a variety of techniques. First we
present the Bogolubov transformation between Rindler and Minkowski
quantizations on two flat spacetimes with topology R3ΓS1 (M_0 and
M_-) for massive Dirac spinors. The two inequivalent spin structures on each
are considered. Results show modifications to the Minkowski space Unruh effect.
This provides a flat space model for the Hawking effect on Kruskal and RP^3
geon black hole spacetimes which is the subject of the rest of this part.
Secondley we present the expectation values of the stress tensor for massive
scalar and spinor fields on M0β and Mββ, and for massive scalar fields on
Minkowski space with a single infinite plane boundary, in the Minkowski-like
vacua.
Finally we investigate particle detector models. We investigate Schlicht's
regularization of the Wightman function and extend it to an arbitrary spacetime
dimension, to quotient spaces of Minkowski space, to non-linear couplings, to a
massless Dirac field, and to conformally flat spacetimes. Secondly we present
some detector responses, including the time dependent responses of inertial and
uniformly accelerated detectors on Mββ and M with boundary with motion
perpendicular to the boundary. Responses are also considered for static
observers in the exterior of the RP^3 geon and comoving observers in RP^3 de
Sitter space, via those in the associated GEMS.Comment: PhD Thesis, 205 page
