Papapetrou Energy-Momentum Tensor for Chern-Simons Modified Gravity
arXiv:gr-qc/0702029 · doi:10.1103/PhysRevD.76.044011
Abstract
We construct a conserved, symmetric energy-momentum (pseudo-)tensor for Chern-Simons modified gravity, thus demonstrating that the theory is Lorentz invariant. The tensor is discussed in relation to other gravitational energy-momentum tensors and analyzed for the Schwarzschild, Reissner-Nordstrom, and FRW solutions. To our knowledge this is the first confirmation that the Reissner-Nordstrom and FRW metrics are solutions of the modified theory.
