Transplanckian energy production and slow roll inflation
Ulf H. Danielsson
In this paper we investigate how the energy density due to a non-standard choice of initial vacuum affects the expansion of the universe during inflation. To do this we introduce s…
Matrix models, 4D black holes and topological strings on non-compact Calabi-Yau manifolds
Ulf H. Danielsson, Martin E. Olsson, Marcel Vonk
We study the relation between c=1 matrix models at self-dual radii and topological strings on non-compact Calabi-Yau manifolds. In particular the special case of the deformed matri…
Lectures on string theory and cosmology
Ulf H. Danielsson
In these lectures I review recent attempts to apply string theory to cosmology, including string cosmology and various models of brane cosmology. In addition, the review includes a…
Type 0A 2D Black Hole Thermodynamics and the Deformed Matrix Model
Ulf H. Danielsson, James P. Gregory, Martin E. Olsson +2
Recently, it has been proposed that the deformed matrix model describes a two-dimensional type 0A extremal black hole. In this paper, the thermodynamics of 0A charged non-extremal…
A matrix model black hole: act II
Ulf H. Danielsson
In this paper we discuss the connection between the deformed matrix model and two dimensional black holes in the light of the new developements involving fermionic type 0A-string t…
