Crisis on Infinite Earths: Short-lived de Sitter Vacua in the String Theory Landscape
Heliudson Bernardo, Suddhasattwa Brahma, Keshav Dasgupta +1
We construct purely non-perturbative anti-de Sitter vacua in string theory which, on uplifting to a de Sitter (dS) one, have a decay time many orders of magnitude smaller than thos…
Solution of the Size and Horizon Problems from Classical String Geometry
Heliudson Bernardo, Robert Brandenberger, Guilherme Franzmann
In a recent paper we developed a string cosmology background from classical string geometry. Here, we show that this background yields a solution to the size and horizon problems o…
String Cosmology backgrounds from Classical String Geometry
Heliudson Bernardo, Robert Brandenberger, Guilherme Franzmann
We introduce a very early universe model based on the thermodynamics of a gas of closed strings in a background which is non-perturbative in . Upon considering the fully -c…
-Cosmology: solutions and stability analysis
Heliudson Bernardo, Guilherme Franzmann
We review O Covariant String Cosmology to all orders in in the presence of matter and study its solutions. We show that the perturbative analysis for a constant dilaton…
