We study one-field open inflationary models in a universe dominated by tachyon matter. In these scenarios, we determine and characterize the existence of the Coleman-De Lucia (CDL) instanton. Also, we study the Lorentzian regime, that is, the period of inflation after tunnelling has occurred
We examine the dynamics of a closed cosmology whose matter source is that of a conformally coupled s...
We investigate the quantum fluctuations of an inflaton field in a two-field model of one-bubble open...
In this paper, we study a tachyon cosmological model based on the dynamics of a 3-brane in the secon...

In this article we study closed inflationary universe models by using a tachyonic field theory. We d...
Warm inflationary universe models in a tachyon field theory are studied. General conditions required...
We show that a large class of two-field models of single-bubble open inflation do not lead to infini...
We study warm-tachyon inflationary universe model in the context of the effective field theory of lo...
In continuation of the papers hep-th/0505012 and hep-th/0508101 we investigate the consequences when...
In this article, our prime objective is to study the inflationary paradigm in the context of the gen...

Abstract We examine the possibility of rolling tachyon to play the dual roll of inflaton at early ep...
For simple inflationary models, we provide a consistent and complete scheme by which the macro-physi...
