Fubini instantons in Dilatonic Einstein-Gauss-Bonnet theory of gravitation
Daeho Ro, Wonwoo Lee, Bum-Hoon Lee
We investigate various types of Fubini instantons in Dilatonic Einstein-Gauss-Bonnet theory of gravitation, which describe the decay of the vacuum state at a hilltop potential thro…

Oscillating Fubini instantons in curved space
Bum-Hoon Lee, Wonwoo Lee, Daeho Ro +1
A Fubini instanton is a bounce solution which describes the decay of a vacuum state located at the top of the tachyonic potential {\it via} the tunneling without a barrier. We inve…

Observational constraints on slow-roll inflation coupled to a Gauss-Bonnet term
Seoktae Koh, Bum-Hoon Lee, Wonwoo Lee +1
We study slow-roll inflation with a Gauss-Bonnet term that is coupled to an inflaton field nonminimally. We investigate the inflationary solutions for a specific type of the nonmin…
