Eternal inflation in swampy landscapes [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 The much-discussed swampland conjectures suggest significant constraints on the properties of string theory landscape and on the nature of the multiverse that this landscape can support. The conjectures are especially constraining for models of inflation; in particular, they exclude the existence of de Sitter (dS) vacua.

Journal of High Energy Physics, 2020 We show how in a matrix inflationary model in which there is a non-minimal coupling between the matrix inflatons and gravity — hence dubbed Non-M-flation — some of the disadvantages of the minimal model can be avoided.

De Sitter diagrammar and the resummation of time
Journal of High Energy Physics, 2020 Light scalars in inflationary spacetimes suffer from logarithmic infrared divergences at every order in perturbation theory. This corresponds to the scalar field values in different Hubble patches undergoing a random walk of quantum fluctuations, leading

Eternal inflation: The inside story [PDF]
Physical Review D, 2006 Motivated by the lessons of black hole complementarity, we develop a causal patch description of eternal inflation. We argue that an observer cannot ascribe a semiclassical geometry to regions outside his horizon, because the large-scale metric is governed by the fluctuations of quantum fields.

Inflation targeting and inflation persistence [PDF]
, 2002 This paper argues that the adoption of an inflation target reduces the persistence of inflation. We develop the theoretical literature on inflation persistence by introducing a Taylor rule for monetary policy into a model of persistence and showing ...

De Sitter quantum breaking, swampland conjectures and thermal strings
Journal of High Energy Physics, 2021 We argue that under certain assumptions the quantum break time approach and the trans-Planckian censorship conjecture both lead to de Sitter swampland constraints of the same functional form.

Axion landscape and natural inflation
Physics Letters B, 2015 Multiple axions form a landscape in the presence of various shift symmetry breaking terms. Eternal inflation populates the axion landscape, continuously creating new universes by bubble nucleation.
