We reply to the recent criticism by Garriga and Tanaka of our proposal that quantum gravitational loop corrections may lead to a secular screening of the effective cosmological constant. Their argument rests upon a renormalization scheme in which the composite operator (R{radical}(-g)-4{lambda}{radical}(-g)){sub ren} is defined to be the trace of the renormalized field equations. Although this is a peculiar prescription, we show that it does not preclude secular screening. Moreover, we show… 

Patient observers and non-perturbative infrared dynamics in inflation

We have previously derived the effect of soft graviton modes on the quantum state of de Sitter using spontaneously broken asymptotic symmetries. In the present paper we prove that this effect can be

Dilaton, screening of the cosmological constant and IR-driven inflation

A bstractIt is known that infrared (IR) quantum fluctuations in de Sitter space could break the de Sitter symmetry and generate time dependent observable effects. In this paper, we consider a

A simplified quantum gravitational model of inflation

Inflationary quantum gravity simplifies drastically in the leading logarithm approximation. We show that the only counterterm which contributes in this limit is the 1-loop renormalization of the

Strong restriction on inflationary vacua from the local gauge invariance III: Infrared regularity of graviton loops

It has been claimed that the super-Hubble modes of the graviton generated during inflation can make loop corrections diverge. Even if we introduce an infrared (IR) cutoff at a comoving scale as an ad

Graviton backreaction on the local cosmological expansion at one-loop order

We compute the graviton one-loop correction to the local expansion rate in cosmological space-times. The calculation presented here is gauge invariant and builds on a recent proposal to explicitly

Is the cosmological constant screened in Liouville gravity with matter

There has been a proposal that infrared quantum effects of massless interacting field theories in de Sitter space may provide time-dependent screening of the cosmological constant. As a concrete

Loops in inflationary correlation functions

We review the recent progress regarding the loop corrections to the correlation functions in the inflationary universe. A naive perturbation theory predicts that the loop corrections generated during

Infrared behaviour of propagators in cosmological spacetimes

In this thesis, we study the infrared behaviour of propagators in Friedmann-Lemaitre-Robertson-Walker (FLRW) spacetimes, of which de Sitter is a special case. For the most part, we are interested in

Semiclassical relations and IR effects in de Sitter and slow-roll space-times

We calculate IR divergent graviton one-loop corrections to scalar correlators in de Sitter space, and show that the leading IR contribution may be reproduced via simple semiclassical consistency



Can infrared gravitons screen Λ

It has been suggested that infrared gravitons in de Sitter space may lead to a secular screening of the effective cosmological constant. This seems to clash with the naive expectation that the

Cosmological long wavelength perturbations

This paper presents an exact solution to the long wavelength perturbations for the scalar modes and for a scalar field theory with arbitrary potential. Locally these modes are coordinate

Quantum Theory of Fields

To say that this is the best book on the quantum theory of fields is no praise, since to my knowledge it is the only book on this subject. But it is a very good and most useful book. The original was
