Initial conditions problem in cosmological inflation revisited
نویسندگان
چکیده
We present first results from a novel numerical relativity code based on tetrad formulation of the Einstein-scalar field equations combined with recently introduced gauge/frame invariant diagnostics. The provide support for argument that inflation does not solve homogeneity and isotropy problem beginning generic initial conditions following big bang.

Initial conditions for inflation
Free scalar fields in de Sitter space have a one-parameter family of states invariant under the de Sitter group, including the standard thermal vacuum. We show that, except for the thermal vacuum, these states are unphysical when gravitational interactions are included. We apply these observations to the quantum state of the inflaton, and find that at best, dramatic fine tuning is required for ...
متن کاملInitial Conditions, Inflation, and Fluctuations
A s you know, four main bodies of evidence affirm the big bang: the dark sky, Hubble expansion, element abundances, and cosmic microwave background radiation (CMBR). Parts 1-4 of this series briefly examined these topics. [1-4] Here we say a few words about the window the CMBR offers into the very early universe, including a brief but crucial epoch of " inflation. " Recall that the CMBR was fir...
متن کاملInitial Conditions for Vector Inflation
Recently, a model of inflation using non-minimally coupled massive vector fields has been proposed. For a particular choice of non-minimal coupling parameter and for a flat FRW model, the model is reduced to the model of chaotic inflation with massive scalar field. We study the effect of non-zero curvature of the universe on the onset of vector inflation. We find that in a curved universe the d...
متن کاملInitial Conditions for Supersymmetric Inflation
We perform a numerical investigation of the fields evolution in the supersymmetric inflationary model based on radiative corrections. Supergravity corrections are also included. We find that, out of all the examined initial data, only about 10% give an adequate amount of inflation and can be considered as ”natural”. Moreover, these successful initial conditions appear scattered and more or less...
متن کاملThe Cosmological Lithium Problem Revisited
After a brief review of the cosmological lithium problem, we report a few recent attempts to find theoretical solutions by our group at Texas A&M University (Commerce & College Station). We will discuss our studies on the theoretical description of electron screening, the possible existence of parallel universes of dark matter, and the use of non-extensive statistics during the Big Bang nucleos...
