Continuity, Localization, and Cosmology in Warped Geometry
Gregory Gabadadze, Daniel Older, David Pirtskhalava
This is the first of two papers studying localization of massive bulk fields on a bane in 5D anti-de Sitter spacetime, and some of their cosmological consequences. Here we focus on…
Resolving the vDVZ and Strong Coupling Problems in Massive Gravity and Bigravity
Gregory Gabadadze, Daniel Older, David Pirtskhalava
As is well known, both massive gravity and bigravity exhibit the linear van Dam-Veltman-Zakharov (vDVZ) discontinuity that is cured classically by the nonlinear Vainshtein mechanis…
Boundary Terms for Massive General Relativity
Gregory Gabadadze, David Pirtskhalava
It is well-known that the presence of a spacetime boundary requires the conventional Einstein-Hilbert (EH) action to be supplemented by the Gibbons-Hawking (GH) boundary term in or…
Rotating superfluids and spinning charged operators in conformal field theory
Gabriel Cuomo, Anton de la Fuente, Alexander Monin +2
We calculate the scaling dimensions of operators with large global charge and spin in 2+1 dimensional conformal field theories. By the state-operator correspondence, these operator…
Gaugid inflation
Federico Piazza, David Pirtskhalava, Riccardo Rattazzi +1
The spectrum of primordial gravitational waves is one of the most robust inflationary observables, often thought of as a direct probe of the energy scale of inflation. We present a…
Stability of Geodesically Complete Cosmologies
Paolo Creminelli, David Pirtskhalava, Luca Santoni +1
We study the stability of spatially flat FRW solutions which are geodesically complete, i.e. for which one can follow null (graviton) geodesics both in the past and in the future w…
