We provide a conceptual unified description of the quantum properties of black holes (BH), elementary particles, de Sitter (dS) and Anti-de Sitter (AdS) string states.The conducting line of argument is the classical–quantum (de Broglie, Compton) duality here extended to the quantum gravity (string) regime (wave–particle–string duality). The semiclassical (QFT) and quantum (string) gravity regimes are respectively characterized and related: sizes, masses, accelerations and temperatures. The… Expand

The physical history of the Universe is completed by including the quantum Planckian and trans-Planckian phase before inflation in the Standard Model of the Universe in agreement with observations.Expand
THE SL(2,R) WZWN STRING MODEL AS A DEFORMED OSCILLATOR AND ITS CLASSICAL-QUANTUM STRING REGIMES
We study the SL(2,R) WZWN string model describing bosonic string theory in AdS3 spacetime as a deformed oscillator together with its mass spectrum and the string modified SL(2,R) uncertaintyExpand

TLDR
The mass formula is found which is also well behaved in all regimes, and the mass spectrum is equal to themass spectrum in flat Minkowski space. Expand

TLDR
The back reaction effect of these strings on the spacetime is found and the self-consistent solution to the Einstein equations for string dominated universes exhibits the realistic matter dominated behaviour R ~ (X0)2/(D-1) for large times and the radiationdominated behaviour R~ (X 0)2/D for early times.
