A link between ghost-free bimetric and Eddington-inspired Born-Infeld theory
Angnis Schmidt-May, Mikael von Strauss
We provide an auxiliary field formulation of the full ghost-free bimetric theory which avoids the explicit presence of a square-root matrix in the action. This description always a…
Absence of ghost in a new bimetric-matter coupling
S. F. Hassan, Mikica Kocic, Angnis Schmidt-May
Interactions in bimetric theory, which can describe gravity in the presence of an extra spin-2 field, are severely constrained by the requirement of the absence of the Boulware-Des…
Mass eigenstates in bimetric theory with matter coupling
Angnis Schmidt-May
In this paper we study the ghost-free bimetric action extended by a recently proposed coupling to matter through a composite metric. The equations of motion for this theory are der…
Particular Solutions in Bimetric Theory and Their Implications
S. F. Hassan, Angnis Schmidt-May, Mikael von Strauss
Ghost-free bimetric theory can describe gravity in the presence of an extra spin-2 field. We study certain aspects of dynamics in this theory: (1) It is shown that if either of the…
Consistent Bimetric Theory and its Application to Cosmology
Angnis Schmidt-May
Recently, the construction of ghost-free nonlinear massive spin-2 interactions solved a long outstanding problem in classical field theory. The consistent formulation requires a se…
Radiative Inflation and Dark Energy RIDEs Again after BICEP2
Pasquale Di Bari, Stephen F. King, Christoph Luhn +2
Following the ground-breaking measurement of the tensor-to-scalar ratio by the BICEP2 collaboration, we perform a statistical analysis of a model that c…
