Generalized Fubini instantons of a self-gravitating scalar field

We investigate the various types of Fubini instantons in the presence of gravity. The Fubini instanton describes the decay of a vacuum state as a consequence of tunneling from the top of a potential to an arbitrary state instead of a rolling down on the tachyonic potential. In this work, we concentr...

Summary:We investigate the various types of Fubini instantons in the presence of gravity. The Fubini instanton describes the decay of a vacuum state as a consequence of tunneling from the top of a potential to an arbitrary state instead of a rolling down on the tachyonic potential. In this work, we concentrate on the tunneling solutions as representing the generalized Fubini instantons of a self-gravitating scalar field with the tachyonic potential having both quartic and quadratic terms.
