The linearized equations of “New Massive Gravity” propagate a parity doublet of massive spin-2 modes in 3D Minkowski spacetime, but a different non-linear extension is made possible by “third-way” consistency. The new equations can be derived from a “Chern-Simons-like” action, as for other 3D massive gravity models, but the new theory is “exotic”: its action is parity odd. This “Exotic Massive Gravity” is the next-to-simplest case in an infinite sequence of third-way consistent 3D massive gravity theories, the simplest being the “Minimal Massive Gravity” alternative to “Topological Massive Gravity”.

Short Bio: Mehmet Ozkan obtained his Ph.D from Department of Physics, Texas A&M University in 2013. He worked as a post-doc in Prof. Eric Bergshoeff’s group at Groningen University. In 2015 he joined the Department of Physics at Istanbul Technical University. His research activities concern supersymmetry and supergravity, string theory and general relativity.
