Three-Form Gauging of axion Symmetries and Gravity
Gia Dvali
Nonlinearly realized Abelian global symmetries can be reformulated as local shift symmetries gauged by three-form gauge fields. The anomalous symmetries of the Standard Model (such…
Infrared Modification of Gravity
Gia Dvali
In this lecture I address the issue of possible large distance modification of gravity and its observational consequences. Although, for the illustrative purposes we focus on a par…
Large scale power and running spectral index in New Old Inflation
Gia Dvali, Shamit Kachru
We have proposed a new class of inflationary scenarios in which the first stage of expansion is driven by "old" false vacuum inflation. This ends by nucleation of a bubble, which t…
New Old Inflation
Gia Dvali, Shamit Kachru
We propose a new class of inflationary solutions to the standard cosmological problems (horizon, flatness, monopole,...), based on a modification of old inflation. These models do…
Dark Energy as a Modification of the Friedmann Equation
Gia Dvali, Michael S. Turner
Dark energy could actually be the manifestation of a modification to the Friedmann equation arising from new physics (e.g., extra dimensions). Writing the correction as $(1-Ω_M)H^α…
Non-Local Modification of Gravity and the Cosmological Constant Problem
Nima Arkani-Hamed, Savas Dimopoulos, Gia Dvali +1
We propose a phenomenological approach to the cosmological constant problem based on generally covariant non-local and acausal modifications of four-dimensional gravity at enormous…
