Fermionic Tachyons as a Source of Dark Energy
arXiv:1807.05871 · doi:10.1016/j.newast.2022.101986
Abstract
A model for the universe on the basis of a self interacting fermionic tachyon field is investigated here. It is shown that, devising a self interaction potential of a proper form, the fermionic tachyon field is capable of producing an accelerating expansion that at late time tends to a constant value which is in consistence with the cosmological constant. This way the introduced fermionic tachyon field can be interpreted as the source of dark energy.
