Gauging Fractons and Linearized Gravity
نویسندگان
چکیده
We consider the covariant gauge field theory of fractons, which describe a new type quasiparticles exhibiting novel and nontrivial properties. In particular, we focus on theoretical peculiarities characterize this theory, starting from fact that, if accept paradigm that quantum theories are defined by their symmetries, fractons unavoidably come together with linearized gravity. The standard Faddeev-Popov procedure to fix leads scalar condition, has two important drawbacks: it is frozen in Landau gravity cannot be obtained as limit. paper adopt tensorially alternative fixing, avoids both problems. allows show physical features, like counting degrees freedom, do not depend particular choice, expected. Moreover, resulting fixed contains limit, differently choice.

Lecture VIII: Linearized gravity
We are now ready to consider the solutions of GR for the case of weak gravitational fields. This encompasses Newtonian gravity, as well as a few extensions thereof. In addition to its importance in e.g. the solar system, our study of linearized gravity will prepare us for the discussion of some of the weak-field experimental tests of GR (Lecture XI). It will also illustrate some of the issues t...
متن کاملS-duality for Linearized Gravity
We develope the analogue of S-duality for linearized gravity in (3+1)-dimensions. Our basic idea is to consider the self-dual (anti-self-dual) curvature tensor for linearized gravity in the context of the Macdowell-Mansouri formalism. We find that the strong-weak coupling duality for linearized gravity is an exact symmetry and implies small-large duality for the cosmological constant. Pacs numb...
متن کاملLinearized Gravity about a Brane
We use the Israel condition to treat carefully the weak-field perturbations due to the presence of matter on a 3-brane embedded between two regions of antide Sitter (AdS) space with different curvature lengths. A four dimensional Newton’s Law only emerges at distances that are large compared to the AdS lengths. When a scalar curvature is included in the brane action, however, it is possible to ...
متن کاملLinearized Gravity in Brane Backgrounds
Abstract A treatment of linearized gravity is given in the Randall-Sundrum background. The graviton propagator is found in terms of the scalar propagator, for which an explicit integral expression is provided. This reduces to the four-dimensional propagator at long distances along the brane, and provides estimates of subleading corrections. Asymptotics of the propagator off the brane yields exp...
متن کاملFactorization and polarization in linearized gravity.
We investigate all the four-body graviton interaction processes: gX → γX, gX → gX, and gg → gg with X as an elementary particle of spin less than two in the context of linearized gravity except the spin-3/2 case. We show explicitly that gravitational gauge invariance and Lorentz invariance cause every four-body graviton scattering amplitude to be factorized. We explore the implications of this ...
