Inflation and dark energy arising from geometrical tachyons

Sudhakar Panda, M. Sami, Shinji Tsujikawa

We study the motion of a BPS D3-brane in the NS5-brane ring background. The radion field becomes tachyonic in this geometrical set up. We investigate the potential of this geometri…

de Sitter thermodynamics and the braneworld

Gianluca Calcagni

The de Sitter thermodynamics of cosmological models with a modified Friedmann equation is considered, with particular reference to high-energy Randall-Sundrum and Gauss-Bonnet bran…

Dark energy and cosmological solutions in second-order string gravity

Gianluca Calcagni, Shinji Tsujikawa, M Sami

We study the cosmological evolution based upon a -dimensional action in low-energy effective string theory in the presence of second-order curvature corrections and a modulus sc…

The fate of (phantom) dark energy universe with string curvature corrections

M. Sami, Alexey Toporensky, Peter V. Tretjakov +1

We study the evolution of (phantom) dark energy universe by taking into account the higher-order string corrections to Einstein-Hilbert action with a fixed dilaton. While the prese…

Coupled dark energy: Towards a general description of the dynamics

Burin Gumjudpai, Tapan Naskar, M. Sami +1

In dark energy models of scalar-field coupled to a barotropic perfect fluid, the existence of cosmological scaling solutions restricts the Lagrangian of the field $\vp$ to $p=X g(X…

Properties of singularities in (phantom) dark energy universe

Shin'ichi Nojiri, Sergei D. Odintsov, Shinji Tsujikawa

The properties of future singularities are investigated in the universe dominated by dark energy including the phantom-type fluid. We classify the finite-time singularities into fo…
