Oscillating instantons as homogeneous tunneling channels
Bum-Hoon Lee, Wonwoo Lee, Dong-han Yeom
In this paper, we study Einstein gravity with a minimally coupled scalar field accompanied with a potential, assuming an O(4) symmetric metric ansatz. We call an Euclidean instanto…

Fubini instantons in curved space
Bum-Hoon Lee, Wonwoo Lee, Changheon Oh +2
We study Fubini instantons of a self-gravitating scalar field. The Fubini instanton describes the decay of a vacuum state under tunneling instead of rolling in the presence of a ta…
