Holographic tachyon model

Understand

We propose in this Letter a holographic model of tachyon dark energy.

• A connection between the tachyon scalar-field and the holographic dark energy is established, and accordingly, the potential of the holographic tachyon field is constructed.
• We show that the holographic evolution of the universe with $c\geqslant 1$ can be described completely by the resulting tachyon model in a certain way.
