New Massive Gravity on de Sitter Space and Black Holes at the Special Point
Gregory Gabadadze, Gaston Giribet, Alberto Iglesias
We study New Massive Gravity on de Sitter background and discuss several interrelated properties: The appearance of an enhanced symmetry point at linearized level where the theory…
Non-perturbative Unitarity of Gravitational Higgs Mechanism
Alberto Iglesias, Zurab Kakushadze
In this paper we discuss massive gravity in Minkowski space via gravitational Higgs mechanism, which provides a non-perturbative definition thereof. Using this non-perturbative def…
Massive Gravity in de Sitter Space via Gravitational Higgs Mechanism
Alberto Iglesias, Zurab Kakushadze
In this paper we discuss massive gravity in de Sitter space via gravitational Higgs mechanism, which provides a nonlinear definition thereof. The Higgs scalars are described by a n…
Lorentz symmetry from a random Hamiltonian
Andreas Albrecht, Alberto Iglesias
We match the density of energy eigenstates of a local field theory with that of a random Hamiltonian order by order in a Taylor expansion. In our previous work we assumed Lorentz s…
The clock ambiguity: Implications and new developments
Andreas Albrecht, Alberto Iglesias
We consider the ambiguity associated with the choice of clock in time reparameterization invariant theories. This arbitrariness undermines the goal of prescribing a fixed set of ph…
Special Massive Spin-2 on de Sitter Space
Gregory Gabadadze, Alberto Iglesias
The theory of a massive spin-2 state on the de Sitter space -- with the mass squared equal to one sixth of the curvature -- is special for two reasons: (i) it exhibits an enhanced…
