Tachyonization of the ΛCDM cosmological model
In this work a tachyonization of the ΛCDM model for a spatially flat Friedmann-Robertson-Walker space-time is proposed. A tachyon field and a cosmological constant are considered as the sources of the gravitational field. Starting from a stability analysis and from the exact solutions for a standard...
