Galileons as the Scalar Analogue of General Relativity
Remko Klein, Mehmet Ozkan, Diederik Roest
We establish a correspondence between general relativity with diffeomorphism invariance and scalar field theories with Galilean invariance: notions such as the Levi-Civita connecti…
Universality Classes of Scale Invariant Inflation
Mehmet Ozkan, Diederik Roest
We investigate the inflationary implications of extensions of Poincare symmetry. The simplest constructions with local scale invariance lead to universal predictions: the spectral…
Supersymmetric Backgrounds and Black Holes in Cosmological New Massive Supergravity
Gokhan Alkac, Luca Basanisi, Eric A. Bergshoeff +2
Using an off-shell Killing spinor analysis we perform a systematic investigation of the supersymmetric background and black hole solutions of the Cosmological New…
Planck constraints on inflation in auxiliary vector modified theories
Mehmet Ozkan, Yi Pang, Shinji Tsujikawa
We show that the universal -attractor models of inflation can be realized by including an auxiliary vector field for the Starobinsky model with the Lagrangian $f(R)=R+R^2/…
