Logarithmic gravity from a very slow roll limit of inflation
Jordan Cotler, Victor Ivo, Juan Maldacena
We study the inflationary no-boundary wavefunction in a ``linear-roll limit,'' in which while the Hubble scale and the slope of the inflaton potential are held fixe…
Renormalization in Liouville gravity and stochastic inflation
Jordan Cotler, Victor Ivo, Juan Maldacena
Motivated by inflation and Liouville theory, we consider random -dimensional geometries characterized by an overall scale factor given in terms of a rando…
One-loop aspects of de Sitter axion wormholes
Victor Ivo, Haifeng Tang
We discuss aspects of the Euclidean path integral around axion-supported de Sitter wormholes, at one-loop order. We numerically compute the phase of the path integral around these…
The phase of charged Nariai solutions
Victor Ivo, Zimo Sun
In this note, we compute the phase of the one-loop Euclidean path integral around charged Nariai solutions in 4 dimensions, including both metric and gauge field fluctuations. Thes…
One loop aspects of Coleman de Luccia instantons at small backreaction
Victor Ivo
We discuss the Euclidean path integral around Coleman de Luccia instantons. We compute their contribution at the one-loop level, at leading order in the small backreaction limit. A…
Physical instabilities and the phase of the Euclidean path integral
Victor Ivo, Juan Maldacena, Zimo Sun
We compute the phase of the Euclidean gravity partition function on manifolds of the form . We find that the total phase is equal to the phase in pure gravity on $S…
The no boundary density matrix
Victor Ivo, Yue-Zhou Li, Juan Maldacena
We discuss a no-boundary proposal for a subregion of the universe. In the classical approximation, this density matrix involves finding a specific classical solution of the equatio…
Comments on the double cone wormhole
Yiming Chen, Victor Ivo, Juan Maldacena
In this paper we revisit the double cone wormhole introduced by Saad, Shenker and Stanford (SSS), which was shown to reproduce the ramp in the spectral form factor. As a first appr…
