Chern-Simons-like Theories of Gravity
Wout Merbis
In this PhD thesis, we investigate a wide class of three-dimensional massive gravity models and show how most of them (if not all) can be brought in a first-order, Chern-Simons-lik…
Interacting spin-2 fields in three dimensions
Hamid R. Afshar, Eric A. Bergshoeff, Wout Merbis
Using the frame formulation of multi-gravity in three dimensions, we show that demanding the presence of secondary constraints which remove the Boulware-Deser ghosts restricts the…
Extended massive gravity in three dimensions
Hamid R. Afshar, Eric A. Bergshoeff, Wout Merbis
Using a first order Chern-Simons-like formulation of gravity we systematically construct higher-derivative extensions of general relativity in three dimensions. The construction en…
Minimal Massive 3D Gravity
Eric Bergshoeff, Olaf Hohm, Wout Merbis +2
We present an alternative to Topologically Massive Gravity (TMG) with the same "minimal" bulk properties; i.e. a single local degree of freedom that is realized as a massive gravit…
Chern-Simons-like Gravity Theories
Eric A. Bergshoeff, Olaf Hohm, Wout Merbis +2
A wide class of three-dimensional gravity models can be put into "Chern-Simons-like" form. We perform a Hamiltonian analysis of the general model and then specialise to Einstein-Ca…
Logarithmic AdS Waves and Zwei-Dreibein Gravity
Eric A. Bergshoeff, Andrés F. Goya, Wout Merbis +1
We show that the parameter space of Zwei-Dreibein Gravity (ZDG) in AdS3 exhibits critical points, where massive graviton modes coincide with pure gauge modes and new `logarithmic'…
