Stability and topological nature of charged Gauss-Bonnet AdS black holes in five dimensions
Imtak Jeon, Bum-Hoon Lee, Wonwoo Lee +1
We investigate the thermodynamics of Reissner-Nordstrom Gauss-Bonnet (RN-GB) black holes in anti-de Sitter (AdS) space with three horizon geometries (k=+1,0,-1) within the grand ca…
Tunneling decay of false vortices with gravitation
Eric Dupuis, Yan Gobeil, Bum-Hoon Lee +5
We study the effect of vortices on the tunneling decay of a symmetry-breaking false vacuum in three spacetime dimensions with gravity. The scenario considered is one in which the i…
Fubini instantons in Dilatonic Einstein-Gauss-Bonnet theory of gravitation
Daeho Ro, Wonwoo Lee, Bum-Hoon Lee
We investigate various types of Fubini instantons in Dilatonic Einstein-Gauss-Bonnet theory of gravitation, which describe the decay of the vacuum state at a hilltop potential thro…
Dynamics of magnetic shells and information loss problem
Bum-Hoon Lee, Wonwoo Lee, Dong-han Yeom
We investigate dynamics of magnetic thin-shells in three dimensional anti de Sitter background. Because of the magnetic field, an oscillatory solution is possible. This oscillating…
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…
