Third Quantization of Kaluza-Klein Cosmology and Compactification
We study on the third quantization of a Kaluza-Klein toy model. In this model time (x) is defined by the scale factor of universe, and the space coordinate (y) is defined by the ratio of the scales of the ordinary space and the internal space. We calculate the number density of the universes created from nothing and examine whether the compactification can be explained statistically by the idea...
متن کاملGravitational Kaluza-Klein Modes in Warped Superstring Compactification
The Kaluza-Klein (KK) modes of graviton are studied in the IIB superstring compactification where the warped geometry is realized at the Klebanov-Strassler (KS) throat. Knowledge of the metric of the KS throat enables us to determine their wave functions with good accuracy, without any further specification of the rest of CalabiYau space, owing to the localization of the KK modes. Mass spectrum...
متن کاملNew Bubble Decays In Kaluza-Klein Theories
We describe new bubble decays in pureD+1 dimensional Einstein theory with two compact directions. The instanton solution is constructed by analytic continuation of the Kaluza-Klein electrically charged black hole solution. We show that the instanton describes the decay of a Kaluza-Klein vacuum MD−1 × T 2 with a non-vanishing torus tilt parameter. The decay is produced by the creation of a bubbl...
متن کاملColliding Kaluza-Klein Bubbles
We construct an exact solution describing the collision of two Kaluza-Klein “bubbles of nothing” in 3+1 dimensions. When the bubbles collide, a curvature singularity forms which is hidden inside an event horizon. However, unlike the formation of ordinary black holes, in this case the spacetime resembles the entire maximally extended Schwarzschild solution. We also point out that there are inequ...
متن کاملSchwinger meets Kaluza-Klein
We study Schwinger pair creation of charged Kaluza-Klein particles from a static KK electric field. We find that the gravitational backreaction of the electric field on the geometry – which is incorporated via the electric KK Melvin solution – prevents the electrostatic potential from overcoming the rest mass of the KK particles, thus impeding the tunneling mechanism which is often thought of a...
