Traversable wormholes in bi-metric gravity
Mostafizur Rahman, Anjan A Sen, Sunil Singh Bohra
The ghost-free bi-metric gravity theory is a viable theory of gravity that explores the interaction between a massless and a massive graviton and can be described in terms of two d…
DBI Galileon and Late time acceleration of the universe
Sampurnanand, Anjan A. Sen
We consider 1+3 dimensional maximally symmetric Minkowski brane embedded in a 1+4 dimensional maximally symmetric Minkowski background. The resulting 1+3 dimensional effective fiel…
Deviation from CDM: Pressure Parametrization
A. A. Sen
Most parametrizations for dark energy involve the equation of state of the dark energy. In this work, we choose the pressure of the dark energy to parametrize. As $p = constant…
Phantom Dark Energy Models with Negative Kinetic Term
Jens Kujat, Robert J. Scherrer, A. A. Sen
We examine phantom dark energy models derived from a scalar field with a negative kinetic term for which V(phi) approaches infinity asymptotically. All such models can be divided i…
Reconstructing K-essence
A. A. Sen
We present a model independent method of reconstructing the Lagrangian for the k-essence field driving the present acceleration of the universe. We consider the simplest k-essence…
Structure formation and CMBR anisotropy spectrum in the inflessence model
A. A. Sen, V. F. Cardone, S. Capozziello +1
The inflessence model has recently been proposed in an attempt to explain both early inflation and present day accelerated expansion within a single mechanism. The model has been s…
