Dualities and Hidden Supersymmetry in String Quantum Cosmology
James E. Lidsey, J. Maharana
A supersymmetric approach to string quantum cosmology based on the non-compact, global duality symmetries of the effective action is developed. An N=2 supersymmetric action is deri…
Reconstructing the Inflaton Potential
Edward W Kolb, Mark Abney, Edmund J Copeland +2
A review is presented of recent work by the authors concerning the use of large scale structure and microwave background anisotropy data to determine the potential of the inflaton…
Black Holes from Blue Spectra
James E. Lidsey, B. J. Carr, J. H. Gilbert
Blue primordial power spectra with a spectral index can lead to a significant production of primordial black holes in the very early Universe. The evaporation of these object…
A Potential Window to the GUT
James E. Lidsey
The possibility that the form of the inflationary potential can be reconstructed from a knowledge of the primordial power spectra of scalar (density) and tensor (gravity wave) pert…
