Tunnelling geometries I. Analyticity, unitarity and instantons in quantum cosmology
A. O. Barvinsky, A. Yu. Kamenshchik
We present a theory of tunnelling geometries originating from the no-boundary quantum state of Hartle and Hawking. We reformulate the no-boundary wavefunction in the representation…

The renormalization group for non-renormalizable theories: Einstein gravity with a scalar field
A. O. Barvinsky, A. Yu. Kamenshchik, I. P. Karmazin
We develop a renormalization-group formalism for non-renormalizable theories and apply it to Einstein gravity theory coupled to a scalar field with the Lagrangian $L=\sqrt{g} [R U(…
