Spacetime foam , CPT anomaly , and photon propagation
Institut für Theoretische Physik, Universität Karlsruhe (TH), 76128 Karlsruhe, Germany Abstract The CPT anomaly of certain chiral gauge theories has been established previously for flat multiply connected spacetime manifolds M of the type R3 ×S1, where the noncontractible loops have a minimal length. In this article, we show that the CPT anomaly also occurs for manifolds where the noncontractib...
متن کاملJa n 19 98 Spacetime foam , Casimir energy and black hole pair creation
We conjecture that the neutral black hole pair production is related to the vacuum fluctuation of pure gravity via the Casimir-like energy. Implications on the foam-like structure of spacetime are discussed.
متن کاملSpacetime Foam: From Entropy and Holography to Infinite Statistics and Nonlocality
Due to quantum fluctuations, spacetime is foamy on small scales. The degree of foaminess is found to be consistent with holography, a principle prefigured in the physics of black hole entropy. It has bearing on the ultimate accuracies of clocks and measurements and the physics of quantum computation. Consistent with existing archived data on active galactic nuclei from the Hubble Space Telescop...
متن کاملPolarized Spacetime Foam
An approximate model of a spacetime foam is presented. It is supposed that in the spacetime foam each quantum handle is like to an electric dipole and therefore the spacetime foam is similar to a dielectric. If we neglect of linear sizes of the quantum handle then it can be described with an operator containing a Grassman number and either a scalar or a spinor field. For both fields the Lagrang...
متن کاملNontrivial Spacetime Topology, Cpt Violation, and Photons
A physical mechanism for CPT violation is reviewed, which relies on chiral fermions, gauge interactions, and nontrivial spacetime topology. The nontrivial topology can occur at the very largest scale (e.g., at the “edge” of the universe) or at the very smallest scale (e.g., from a hypothetical spacetime foam). The anomalous effective gauge field action includes, most likely, a CPT–odd Chern–Sim...
