Moduli Stabilization and the Holographic RG for AdS and dS
Xi Dong, Bart Horn, Eva Silverstein +1
We relate moduli stabilization () in the bulk of or to basic properties of the Wilsonian effective action in the holographic dual theory on : the sin…
Perturbative Critical Behavior from Spacetime Dependent Couplings
Xi Dong, Bart Horn, Eva Silverstein +1
We find novel perturbative fixed points by introducing mildly spacetime-dependent couplings into otherwise marginal terms. In four-dimensional QFT, these are physical analogues of…
The Benefits of Stress: Resolution of the Lifshitz Singularity
Ning Bao, Xi Dong, Sarah Harrison +1
Through the AdS/CFT correspondence, Lifshitz spacetimes describe field theories with dynamical scaling (). Although curvature invariants are small, the Lifshitz metric ex…
Unitarity bounds and RG flows in time dependent quantum field theory
Xi Dong, Bart Horn, Eva Silverstein +1
We generalize unitarity bounds on operator dimensions in conformal field theory to field theories with spacetime dependent couplings. Below the energy scale of spacetime variation…
