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…
c-theorem of the entanglement entropy
Chanyong Park, Daeho Ro, Jung Hun Lee
We holographically investigate the renormalization group flow in a two-dimensional conformal field theory deformed by a relevant operator. If the relevant operator allows another f…
Quantum entanglement in inflationary cosmology
Seoktae Koh, Jung Hun Lee, Chanyong Park +1
We investigate the holographic quantum entanglement of a visible universe in an inflationary cosmology. To do so, we consider an AdS space with a dS boundary which represents an ex…
