“…Another possibility one could think of in this context is higher-dimensional spin-2 fields; once the reduction (or compactification) to four dimensions is performed, the higher-dimensional fields turn into a four-dimensional tower of massive states, with masses set by the parameters of the compactification scheme / mechanism [36,37]. In this case the coupling to ordinary matter may be non-universal; however our results can be generalised to this case.…”

Binary pulsars can be excellent probes of ultra-light dark matter. We consider the scenario where the latter is represented by a spin-2 field. The coherent oscillations of the dark matter field perturb the dynamics of binary systems, leading to secular effects for masses that resonate with the binary systems. For the range 10 −23 eV m 10 −17 eV we show that current timing data could potentially constrain the universal coupling strength of dark matter to ordinary matter at the level of α 10 −5 . :1909.13814v1 [astro-ph.HE] arXiv

Abstract:We extend the techniques of double field theory to more general gravity theories and U-duality symmetries, having in mind applications to the complete D = 11 supergravity. In this paper we work out a (3 + 3)-dimensional 'U-duality covariantization' of D = 4 Einstein gravity, in which the Ehlers group SL(2, R) is realized geometrically, acting in the 3 representation on half of the coordinates. We include the full (2 + 1)-dimensional metric, while the 'internal vielbein' is a coset representative of SL(2, R)/SO(2) and transforms under gauge transformations via generalized Lie derivatives. In addition, we introduce a gauge connection of the 'C-bracket', and a gauge connection of SL(2, R), albeit subject to constraints. The action takes the form of (2 + 1)-dimensional gravity coupled to a Chern-Simons-matter theory but encodes the complete D = 4 Einstein gravity. We comment on generalizations, such as an 'E 8(8) covariantization' of M-theory.

“…We give the general procedure and illustrate it with the simplest non-trivial case, which is spin-2. The spin-2 equations in curved space can also be obtained by Kaluza-Klein reduction of Einstein gravity in one higher dimension [6]. The loop variable method however can be just as easily applied to arbitrarily high spin fields.…”

Using the loop variable formalism as applied to a sigma model in curved target space, we give a systematic method for writing down gauge and generally covariant equations of motion for the modes of the free open string in curved space. The equations are obtained by covariantizing the flat space equation and then demanding gauge invariance, which introduces additional curvature couplings. As an illustration of the procedure, the spin two case is worked out explicitly.
