Fuzzy Euclidean wormholes in the inflationary universe
Pisin Chen, Daeho Ro, Dong-han Yeom
In this paper, we investigate complex-valued Euclidean wormholes in the Starobinsky inflation. Due to the properties of the concave inflaton potential, the classicality condition a…
Expanded evasion of the black hole no-hair theorem in dilatonic Einstein-Gauss-Bonnet theory
Bum-Hoon Lee, Wonwoo Lee, Daeho Ro
We study a hairy black hole solution in the dilatonic Einstein-Gauss-Bonnet theory of gravitation, in which the Gauss-Bonnet term is non-minimally coupled to the dilaton field. Hai…
Dilaton Field Released under Collision of Dilatonic Black Holes with Gauss-Bonnet Term
Bogeun Gwak, Daeho Ro
We investigate the upper limit of the gravitational radiation released upon the collision of two dilatonic black holes by analyzing the Gauss-Bonnet term. Dilatonic black holes hav…
Spin Interaction under the Collision of Two Kerr-(anti-)de Sitter Black Holes
Bogeun Gwak, Daeho Ro
We have investigated spin interaction under the collision of Kerr-(anti-)de Sitter black holes. The potential of a spin interaction is dependent on the relative rotating directions…
Instability of Charged Anti-de Sitter Black Holes
Bogeun Gwak, Bum-Hoon Lee, Daeho Ro
We study the instability of charged anti-de Sitter black holes in four or higher-dimension under fragmentation. The instability of fragmentation breaks the black hole into two blac…
