Holographic flows from CFT to the Kasner universe

Frenkel, Alexander, Hartnoll, Sean A., Kruthoff, Jorrit et al.

Understand

The Schwarzschild singularity is known to be classically unstable.

  • We demonstrate a simple holographic consequence of this fact, focusing on a perturbation that is uniform in boundary space and time.
  • Deformation of the thermal state of the dual CFT by a relevant operator triggers a nonzero temperature holographic renormalization group flow in the bulk.
  • This flow continues smoothly through the horizon and, at late interior time, deforms the Schwarzschild singularity into a more general Kasner universe.
