Energy-momentum density in small regions: the classical pseudotensors
Lau Loi So, James M. Nester, Hsin Chen
The values for the gravitational energy-momentum density, given by the famous classical pseudotensors: Einstein, Papapetrou, Landau-Lifshitz, Bergmann-Thompson, Goldberg, Møller, a…
Torsion Cosmology and the Accelerating Universe
Kun-Feng Shie, James M. Nester, Hwei-Jang Yo
Investigations of the dynamic modes of the Poincare gauge theory of gravity found only two good propagating torsion modes; they are effectively a scalar and a pseudoscalar. Cosmolo…
Quasi-local energy for cosmological models
Chiang-Mei Chen, Jian-Liang Liu, James M. Nester
First we briefly review our covariant Hamiltonian approach to quasi-local energy, noting that the Hamiltonian-boundary-term quasi-local energy expressions depend on the chosen boun…
On source coupling and the teleparallel equivalent to GR
Lau Loi So, James M. Nester
Alternatives to the usual general relativity (GR) Riemannian framework include Riemann-Cartan and teleparallel geometry. The ``teleparallel equivalent of GR" (TEGR, aka GR…
Gravitational energy-momentum in small regions according to Moller's tetrad expression
Lau Loi So, James M. Nester
Moller's tetrad gravitational energy-momentum "tensor" is evaluated for a small vacuum region using an orthonormal frame adapted to Riemann normal coordinates. We find that it does…
Quasi-local energy-momentum and energy flux at null infinity
Xiaoning Wu, Chiang-Mei Chen, James M. Nester
The null infinity limit of the gravitational energy-momentum and energy flux determined by the covariant Hamiltonian quasi-local expressions is evaluated using the NP spin coeffici…
