A new cosmology of a crystallization process (decoherence) from the surrounding quantum soup provides heuristics to unify general relativity and quantum physics by solid state physics [PDF]

open access: closed, 2021
We explore a cosmology where the Big Bang singularity is replaced by a condensation event of interacting strings. We study the transition from an uncontrolled, chaotic soup (“before”) to a clearly interacting “real world”. Cosmological inflation scenarios do not fit current observations and are avoided.

General relativity and quantum fields: some aspects of black holes physics and cosmology in Lovelock gravity, de Sitter spaces and extra-dimensions [PDF]

open access: green, 2006
At the frontier of modern physics, the black hole evaporation process is undoubtedly the most favored phenomenon to get informations on quantum gravity. After a brief introduction to Einstien's General Relativity and to one of its extension as a Taylor expansion in scalar curvature, this thesis deals with the Hawking process focusing on the computation

General relativity, quantum mechanics and spacetime with particular lower surface: A credible alternative to standard model of cosmology

open access: closed, 2021
In a previous paper, we had introduced the concept of differentiable and smooth spacetime with particular lower surface S_€ playing the role of a kind of smallest (non-zero) surface making sense.We had also shown in another paper that quantum mechanics leads to an amendment of the classical metric describing a body of energy E.In the present paper; we ...
