Tachyonic open inflationary universes
arXiv:gr-qc/0703026 · doi:10.1016/j.physletb.2007.02.011
Abstract
We study one-field open inflationary models in a universe dominated by tachyon matter. In these scenarios, we determine and characterize the existence of the Coleman-De Lucia (CDL) instanton. Also, we study the Lorentzian regime, that is, the period of inflation after tunnelling has occurred.
