Fake Conformal Symmetry in Conformal Cosmological Models
R. Jackiw, So-Young Pi
We examine the local conformal invariance (Weyl invariance) in tensor-scalar theories used in recently proposed conformal cosmological models. We show that the Noether currents ass…
Weyl Invariant Dynamics in 3 Dimensions
R. Jackiw
We analyze a variety of Weyl invariant dynamical problems in three dimensions.
Cotton Blend Gravity Waves
S. Deser, R. Jackiw, S. -Y. Pi
We study conformal gravity in d=2+1, where the Cotton tensor is equated to a--necessarily traceless--matter stress tensor, for us that of the improved scalar field. We first solve…
Scalar Field for Breaking Lorentz and Diffeomorphism Invariance
R. Jackiw
A scalar field can be inserted in Maxwell and/or Einstein theory to effect symmetry breaking. Consequences of such a modification are discussed. Possible dynamics for the scalar fi…
Chern-Simons Modification of General Relativity
R. Jackiw, S. -Y. Pi
General relativity is extended by promoting the three-dimensional gravitational Chern-Simons term to four dimensions. This entails choosing an embedding coordinate v_μ-- an externa…
Solutions to a Quantal Gravity-Matter Field Theory on a Line
Roman Jackiw
Solutions to a scalar-tensor (dilaton) quantum gravity theory, interacting with quantized matter, are described. Dirac quantization is frustrated by quantal anomalies in the constr…
