From Asymptotic Safety to Dark Energy
Changrim Ahn, Chanju Kim, Eric V. Linder
We consider renormalization group flow applied to the cosmological dynamical equations. A consistency condition arising from energy-momentum conservation links the flow parameters…
Dark Energy Properties in DBI Theory
Changrim Ahn, Chanju Kim, Eric V. Linder
The Dirac-Born-Infeld (DBI) action from string theory provides several new classes of dark energy behavior beyond quintessence due to its relativistic kinematics. We constrain para…
Cosmological Constant Behavior in DBI Theory
Changrim Ahn, Chanju Kim, Eric V. Linder
Cosmological constant behavior can be realized as solutions of the Dirac-Born-Infeld (DBI) action within Type IIB string theory and the AdS/CFT correspondence. We derive a family o…
Deformed Type 0A Matrix Model and Super-Liouville Theory for Fermionic Black Holes
Changrim Ahn, Chanju Kim, Jaemo Park +2
We consider a model in the fermionic black hole background. For this purpose we consider a model which contains both the N=1 and the N=2 super-Liouville interactions.…
Duality in N=2 Super-Liouville Theory
Changrim Ahn, Chanju Kim, Chaiho Rim +1
In this paper we consider a strong-weak coupling duality of the N=2 super-Liouville field theory (SLFT). Without the self-duality found in other Liouville theories, the N=2 SLFT, w…
RG Flows from Super-Liouville Theory to Critical Ising Model
Changrim Ahn, Chanju Kim, Chaiho Rim +1
We study an integrable deformation of the super-Liouville theory which generates a RG flows to the critical Ising model as the IR fixed point. This model turns out to be a supersym…
