Supergravity, Dark Energy and the Fate of the Universe
Renata Kallosh, Andrei Linde, Sergey Prokushkin +1
We propose a description of dark energy and acceleration of the universe in extended supergravities with de Sitter (dS) solutions. Some of them are related to M-theory with non-com…
M-theory, Cosmological Constant and Anthropic Principle
Renata Kallosh, Andrei Linde
We discuss the theory of dark energy based on maximally extended supergravity and suggest a possible anthropic explanation of the present value of the cosmological constant and of…
Supergravity, M theory and Cosmology
Renata Kallosh
We discuss some recent attempts to reconcile cosmology with supergravity and M/string theory. First of all, we point out that in extended supergravities the scalar masses are quant…
D3/D7 Inflationary Model and M-theory
Keshav Dasgupta, Carlos Herdeiro, Shinji Hirano +1
A proposal is made for a cosmological D3/D7 model with a constant magnetic flux along the D7 world-volume. It describes an N=2 gauge model with Fayet-Iliopoulos terms and the poten…
