Role of Tachyonic Field in Accelerating Universe in Presence of Perfect Fluid
Writambhara Chakraborty, Ujjal Debnath
Recently tachyonic field has been depicted as dark energy model to represent the present acceleration of the Universe. In this paper we have considered mixture of tachyonic fluid w…
General relativistic plasma in higher dimensional space time
D. Panigrahi, S. Chatterjee
The well known (3+1) decomposition of Thorne and Macdonald is invoked to write down the Einstein-Maxwell equations generalised to (d+1) dimensions and also to formulate the plasma…
Interaction between scalar field and ideal fluid with inhomogeneous equation of state
Writambhara Chakraborty, Ujjal Debnath
In this letter we study a model of interaction between the scalar field and an inhomogeneous ideal fluid. We have considered two forms of the ideal fluid and a power law expansion…
Accelerating Universe from an Evolving Lambda in Higher Dimension
D. Panigrahi, S. Chatterjee
We find exact solutions in five dimensional inhomogeneous matter dominated model with a varying cosmological constant. Adjusting arbitrary constants of integration one can also ach…
