Born-Infeld Gravity with a Unique Vacuum and a Massless Graviton
Ibrahim Gullu, Tahsin Cagri Sisman, Bayram Tekin
We construct an n-dimensional Born-Infeld type gravity theory that has the same properties as Einstein's gravity in terms of the vacuum and particle content: Namely, the theory has…
Born-Infeld Gravity with a Massless Graviton in Four Dimensions
Ibrahim Gullu, Tahsin Cagri Sisman, Bayram Tekin
We construct Born-Infeld (BI) type gravity theories which describe tree-level unitary (non-ghost and non-tachyonic) massless spin-2 modes around their maximally symmetric vacua in…
Spectra, vacua and the unitarity of Lovelock gravity in D-dimensional AdS spacetimes
Tahsin Cagri Sisman, Ibrahim Gullu, Bayram Tekin
We explicitly confirm the expectation that generic Lovelock gravity in D dimensions has a unitary massless spin-2 excitation around any one of its constant curvature vacua just lik…
AdS Waves as Exact Solutions to Quadratic Gravity
Ibrahim Gullu, Metin Gurses, Tahsin Cagri Sisman +1
We give an exact solution of the quadratic gravity in D dimensions. The solution is a plane fronted wave metric with a cosmological constant. This metric solves not only the full q…
All unitary cubic curvature gravities in D dimensions
Tahsin Cagri Sisman, Ibrahim Gullu, Bayram Tekin
We construct all the unitary cubic curvature gravity theories built on the contractions of the Riemann tensor in D -dimensional (anti)-de Sitter spacetimes. Our construction is bas…
All Bulk and Boundary Unitary Cubic Curvature Theories in Three Dimensions
Ibrahim Gullu, Tahsin Cagri Sisman, Bayram Tekin
We construct all the bulk and boundary unitary cubic curvature parity invariant gravity theories in three dimensions in (anti)-de Sitter spaces. For bulk unitarity, our constructio…
