The stringy nature of the 2d type-0A black hole
Martin E. Olsson
We investigate the thermodynamics of the RR charged two-dimensional type-0A black hole background at finite temperature, and compare with known 0A matrix model results. It has been…
4D black holes and holomorphic factorization of the 0A matrix model
Ulf H. Danielsson, Niklas Johansson, Magdalena Larfors +2
In this letter, we relate the free energy of the 0A matrix model to the sum of topological and anti-topological string amplitudes. For arbitrary integer multiples of the matrix mod…
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…
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…
On Thermalization in de Sitter Space
Ulf H. Danielsson, Martin E. Olsson
We discuss thermalization in de Sitter space and argue, from two different points of view, that the typical time needed for thermalization is of order , where …
Miracles and complementarity in de Sitter space
Ulf H. Danielsson, Daniel Domert, Martin Olsson
In this paper we consider a scenario, consisting of a de Sitter phase followed by a phase described by a scale factor , where , which can be viewed as an i…
