Local Expansion Mechanisms for Quantum-Scale Wormholes
Philipp Dorau, Albert Much
Quantum models of spacetime have been conjectured to hypothetically allow for the formation of Planck scale wormholes. Building on the proposal of Morris, Thorne, and Yurtsever tha…
Global Hyperbolicity and Self-adjointness
Markus B. Fröb, Albert Much, Kyriakos Papadopoulos
We show that the spatial part of the Klein-Gordon operator is an essentially self-adjoint operator on the Cauchy surfaces of various classes of spacetimes. Our proof employs the in…
A Deformation Quantization for Non-Flat Spacetimes and Applications to QFT
Albert Much
We provide a deformation quantization, in the sense of Rieffel, for \textit{all} globally hyperbolic spacetimes with a Poisson structure. The Poisson structures have to satisfy Fed…
Quantum Spacetimes from General Relativity?
Albert Much
We introduce a non-commutative product for curved spacetimes, that can be regarded as a generalization of the Rieffel (or Moyal-Weyl) product. This product employs the exponential…
