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…
Matrix models from localization of five-dimensional supersymmetric noncommutative U(1) gauge theory
Bum-Hoon Lee, Daeho Ro, Hyun Seok Yang
We study localization of five-dimensional supersymmetric gauge theory on where is a noncommutative (NC) plane. The…
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…
Instantons near a tachyonic top in anti de Sitter and the no-boundary regulator
Bum-Hoon Lee, Wonwoo Lee, Daeho Ro +1
We investigate instantons near a tachyonic top in an anti de Sitter (AdS) background. If the mass scale around the hill-top is above the Breitenlohner-Freedman (BF) bound, then the…
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…
