Notes on a Gaussian-Based Distribution Algebra for the Non-linear Wave Equation of the Shift Vector in Quantum Foam

Claes Cramer

We develop a non-linear distributional renormalisation algebra for Gaussian Quantum Foam, built from sequences of scaled Gaussians on spacelike hypersurfaces of homotopic, globally…

Classical Aspects of a Distributional 3+1 Foam Model

Claes Cramer

A 3+1 spacetime, with a shift vector that is the unique fundamental solution to the linearized wave operator, is introduced to model an interpretation of Wheeler's layman's analogy…

The thermal and two-particle stress-energy must be ill-defined on the 2-d Misner space chronology horizon

Claes R Cramer, Bernard S. Kay

We show that an analogue of the (four dimensional) image sum method can be used to reproduce the results, due to Krasnikov, that for the model of a real massless scalar field on th…

Stress-Energy Must be Singular on the Misner Space Horizon even for Automorphic Fields

Claes R Cramer, Bernard S. Kay

We use the image sum method to reproduce Sushkov's result that for a massless automorphic field on the initial globally hyperbolic region of Misner space, one can always find…

Using the Uncharged Kerr Black Hole as a Gravitational Mirror

Claes R Cramer

We extend the study of the possibility to use the Schwarzschild black hole as a gravitational mirror to the more general case of an uncharged Kerr black hole. We use the null geode…

Photon propagation in a stationary warp drive space-time

Claes R Cramer

We simplify the warp drive space-time so that it becomes stationary and the distorsion becomes one-dimensional and static. We use this simplified warp drive space-time as a backgro…
