The nucleation of false vacuum bubbles with compact geometries
Bum-Hoon Lee, Chul H. Lee, Wonwoo Lee +1
We investigate and classify the possible types of false vacuum bubbles in Einstein gravity. The false vacuum bubbles can occur only if gravity is taken into account. We show that t…
Oscillating instanton solutions in curved space
Bum-Hoon Lee, Chul H. Lee, Wonwoo Lee +1
We investigate oscillating instanton solutions of a self-gravitating scalar field between degenerate vacua. We show that there exist O(4)-symmetric oscillating solutions in a de Si…
Instanton solutions mediating tunneling between the degenerate vacua in curved space
Bum-Hoon Lee, Chul H. Lee, Wonwoo Lee +1
We investigate the instanton solution between the degenerate vacua in curved space. We show that there exist -symmetric solutions not only in de Sitter but also in both flat…
Dynamics of false vacuum bubbles with nonminimal coupling
Bum-Hoon Lee, Chul H. Lee, Wonwoo Lee +2
We study the dynamics of false vacuum bubbles. A nonminimally coupled scalar field gives rise to the effect of negative tension. The mass of a false vacuum bubble from outside obse…
Bremsstrahlung Radiation At a Vacuum Bubble Wall
Jae-Weon Lee, Kyungsub Kim, Chul H. Lee +1
When charged particles collide with a vacuum bubble, they can radiate strong electromagnetic waves due to rapid deceleration. Owing to the energy loss of the particles by this brem…
The false vacuum bubble nucleation due to a nonminimally coupled scalar field
Wonwoo Lee, Bum-Hoon Lee, Chul H. Lee +1
We study the possibility of forming the false vacuum bubble nucleated within the true vacuum background via the true-to-false vacuum phase transition in curved spacetime. We consid…
