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…

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…

Real observers solving imaginary problems

Juan Maldacena

The sphere partition function is one of the simplest euclidean gravity computations. It is usually interpreted as count of states. However, the one loop gravity correction contains…

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 no boundary wavefunction and slow roll inflation

Juan Maldacena

We review aspects of the Hartle-Hawking no boundary geometry in the context of slow roll inflation. We give an analytic approximation to the geometry and we explain the rationale f…

Three Point Amplitudes in Matrix Theory

Aidan Herderschee, Juan Maldacena

We compute the three graviton amplitude in the Banks-Fischler-Shenker-Susskind matrix model for M-theory. Even though the three point amplitude is determined by super Poincare inva…

Soft Theorems in Matrix Theory

Aidan Herderschee, Juan Maldacena

We show that the Banks-Fischler-Shenker-Susskind matrix model for M-theory obeys the leading and subleading soft theorems expected from eleven-dimensional supergravity. The sublead…
