II. (ANTI-)DE SITTER SPACE-TIMES A simple way to understand the n-dimensional De Sitter space (dS n) is by its embedding in a (n+1)-dimensional at space Rn;1 with Cartesian coordinates 2001-09-30 · These lectures present an elementary discussion of some background material relevant to the problem of de Sitter quantum gravity. The first two lectures discuss the classical geometry of de Sitter space and properties of quantum field theory on de Sitter space, especially the temperature and entropy of de Sitter space. The final lecture contains a pedagogical discussion of the appearance of 230 B Allen / Phase transltlons tn De Sitter space Each observer in De Sitter space has an event horizon, which he observes radiating a thermal spectrum of particles [5], at a temperature H/2rr. This is the lowest equilibrium temperature that any matter can have. So as the matter cools, it In this module we derive constant curvature de Sitter and anti de Sitter solutions of the Einstein equations with non-zero cosmological constant.

It is shown that the Debye mass appears only in the case of alpha-vacuum in the Expanding Poincare Patch. It can be shown either by direct de Sitter Space The project at KCL I am currently working on involves attempting to do quantum field theory (the stuff the use at CERN), in a curved background “Spacetime” called de Sitter space. An additional causal feature of de Sitter space is that every inextendible null geodesic in it is globally achronal, i.e., never enters into its own chronological future or past. Such null geodesics are referred to as null lines.

An additional causal feature of de Sitter space is that every inextendible null geodesic in it is globally achronal, i.e., never enters into its own chronological future or past. Such null geodesics are referred to as null lines. As it turns out, the occurrence of null lines is a very particular feature of de Sitter space.
