非均匀状态方程下标量场与理想流体的相互作用

Interaction between scalar field and ideal fluid with inhomogeneous equation of state

Writambhara Chakraborty, Ujjal Debnath

摘要:

本文研究了标量场与非均匀理想流体相互作用的模型。我们考虑了理想流体的两种形式和标度因子的幂律展开。我们已经解出了能量密度的方程。我们还表明,除了作为一个暗能量模型来解释宇宙加速,这个模型显示了一个衰减的性质的标量场潜力和相互作用参数。

英文摘要:

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 for the scale factor. We have solved the equations for the energy densities. Also we show that besides being a dark energy model to explain the cosmic acceleration, this model shows a decaying nature of the scalar field potential and the interaction parameter.
