相互作用速子标量场

Interacting tachyonic scalar field

A Kundu, S D Pathak, V K Ojha

摘要:

我们讨论了暗能量和物质之间的耦合,考虑一个均匀的快子标量场作为候选的暗能量。在假设耦合强度与哈勃参数和能量密度成线性关系的条件下,得到了标度因子的函数形式。我们还估算了不同耦合常数值下的宇宙年龄。

英文摘要:

We discuss the coupling between dark energy and matter by considering a homogeneous tachyonic scalar field as a candidate for dark energy. We obtained the functional form of scale factor by assuming that the coupling strength depends linearly on the Hubble parameter and energy density. We also estimated the cosmic age of the universe for different values of coupling constant.
