Description

The concept of dark energy has been proposed to explain the observed accelerated expansion of the universe. One popular and trivial choice of source of dark energy is the scalar field. We choose the tachyonic field, one of the scalar fields, as a candidate for dark energy and discuss it in a model where matter and dark energy (tachyonic scalar field) are allowed to interact with each other. The age of the universe and the coupling strength of the interaction has been estimated and discussed.
