The cosmological BCS mechanism and the Big Bang Singularity
arXiv:0807.4468 · doi:10.1103/PhysRevD.80.023501
Abstract
We provide a novel mechanism that resolves the Big Bang Singularity present in FRW space-times without the need for ghost fields. Building on the fact that a four-fermion interaction arises in General Relativity when fermions are covariantly coupled, we show that at early times the decrease in scale factor enhances the correlation between pairs of fermions. This enhancement leads to a BCS-like condensation of the fermions and opens a gap dynamically driving the Hubble parameter to zero and results in a non-singular bounce, at least in some special cases.
