Graceful exit from a stringy landscape via MSSM inflation
Rouzbeh Allahverdi, Andrew R. Frey, Anupam Mazumdar
The cosmological evolution of the string landscape is expected to consist of multiple stages of old inflation with large cosmological constant ending by tunnelling. Old inflation h…
Cosmological constraints on string scale and coupling arising from tachyonic instability
Kari Enqvist, Asko Jokinen, Anupam Mazumdar +2
We demonstrate that string motivated inflation ending via tachyonic instability leaves a detectable imprint on the cosmic microwave background (CMB) radiation by virtue of the exci…
Inflation from multiple flat directions
Asko Jokinen, Anupam Mazumdar
The paper has been withdrawn by authors. The issues studied in this paper were changed so much that we have published a new paper considering these issues. See hep-th/0406074
Low scale inflation with large number of e-foldings
Anupam Mazumdar
In this paper we illustrate an interesting example of low scale inflation with an extremely large number of e-foldings. This realization can be implemented easily in hybrid inflati…
Inflation and Brane Gases
Robert Brandenberger, Damien A. Easson, Anupam Mazumdar
We investigate a new way of realizing a period of cosmological inflation in the context of brane gas cosmology. It is argued that a gas of co-dimension one branes, out of thermal e…
