de Sitter instanton from Euclidean dynamical triangulations

چکیده

We study the emergence of de Sitter space in Euclidean dynamical triangulations (EDT). Working within semi-classical approximation, it is possible to relate lattice parameters entering simulations partition function quantum gravity. verify that EDT geometries behave semi-classically, and by making contact with Hawking-Moss instanton solution for function, we show how extract a value renormalized Newton's constant from simulations. This consistent our previous determination coming interaction scalar particles. That same universal appears these two different sectors theory strong indication provides viable formulation

De Sitter Space Without Dynamical Quantum Fluctuations

We argue that, under certain plausible assumptions, de Sitter space settles into a quiescent vacuum in which there are no dynamical quantum fluctuations. Such fluctuations require either an evolving microstate, or time-dependent histories of out-of-equilibrium recording devices, which we argue are absent in stationary states. For a massive scalar field in a fixed de Sitter background, the cosmi...

ITEP-LAT/2003-31 10 D Euclidean dynamical triangulations.

We investigate numerically 10-dimensional Euclidean quantum gravity in the framework of the dynamical triangulation approach. For the considered values of the gravitational coupling we observed two phases, the behavior of which is found to be similar to that of the crumpled and elongated phases of 3, 4 and 5 dimensional models.

Dynamical Behavior of dilaton in de Sitter space

We study the dynamical behavior of the dilaton in the background of three-dimensional Kerr-de Sitter space which is inspired from the low-energy string effective action. The perturbation analysis around the cosmological horizon of Kerr-de Sitter space reveals a mixing between the dilaton and other fields. Introducing a gauge (dilaton gauge), we can disentangle this mixing completely and obtain ...

Super-Hubble de Sitter Fluctuations and the Dynamical RG

Perturbative corrections to correlation functions for interacting theories in de Sitter spacetime often grow secularly with time, due to the properties of fluctuations on super-Hubble scales. This growth can lead to a breakdown of perturbation theory at late times. We argue that Dynamical Renormalization Group (DRG) techniques provide a convenient framework for interpreting and resumming these ...

De Sitter and Schwarzschild-de Sitter According to Schwarzschild and De Sitter

When de Sitter first introduced his celebrated spacetime, he claimed, following Schwarzschild, that its spatial sections have the topology of the real projective space IRP 3 (that is, the topology of the group manifold SO(3)) rather than, as is almost universally assumed today, that of the sphere S. (In modern language, Schwarzschild was disturbed by the non-local correlations enforced by S geo...
