Tachyon field in loop cosmology

Abstract

The evolutionary pictures of tachyon field in modified loop cosmology have been investigated. We present the dynamical behavior of the tachyon field associated with an exponential potential and find that the pre-inflation dynamics are very similar in both modified loop cosmology and standard loop quantum cosmology. In addition, tachyonic inflation in modified loop cosmology models are discussed, and we find that the probability of inflation in modified loop cosmology is very closer to 1.
