      General relativity may be formulated in terms of tetrad fields and of the torsion tensor, i.e. in an alternative geometrical formulation as shown in the review by J.W. Maluf (pp. 339–357). This teleparallel equivalent of general relativity has been expressed on the front page in an artistic vision by G. Schulz (Fussgoenheim, Germany).

      Observational effects from quantum cosmology (pages 323–338)

      Gianluca Calcagni

      Article first published online: 12 MAR 2013 | DOI: 10.1002/andp.201200227

      The status of quantum cosmologies as testable models of the early universe is assessed in the context of inflation. While traditional Wheeler–DeWitt quantization is unable to produce sizable effects in the cosmic microwave background, the more recent loop quantum cosmology can generate potentially detectable departures from the standard cosmic spectrum. Thus, present observations constrain the parameter space of the model, which could be made falsifiable by near-future experiments.

      The teleparallel equivalent of general relativity (pages 339–357)

      José W. Maluf

      Article first published online: 15 MAR 2013 | DOI: 10.1002/andp.201200272

      A review of the teleparallel equivalent of general relativity is presented. It is emphasized that general relativity may be formulated in terms of the tetrad fields and of the torsion tensor, and that this geometrical formulation leads to alternative insights into the theory. The equivalence with the standard formulation in terms of the metric and curvature tensors takes place at the level of field equations. The review starts with a brief account of the history of teleparallel theories of gravity. Then the ordinary interpretation of the tetrad fields as reference frames adapted to arbitrary observers in space–time is discussed, and the tensor of inertial accelerations on frames is obtained. It is shown that the Lagrangian and Hamiltonian field equations allow us to define the energy, momentum and angular momentum of the gravitational field, as surface integrals of the field quantities. In the phase space of the theory, these quantities satisfy the algebra of the Poincaré group.

    1. Next-to-next-to-leading order post-Newtonian linear-in-spin binary Hamiltonians (pages 359–394)

      Johannes Hartung, Jan Steinhoff and Gerhard Schäfer

      Article first published online: 24 APR 2013 | DOI: 10.1002/andp.201200271

      The next-to-next-to-leading order post-Newtonian spin-orbit and spin(1)-spin(2) Hamiltonians for binary compact objects in general relativity are derived. The Arnowitt-Deser-Misner canonical formalism and its generalization to spinning compact objects in general relativity are presented and a fully reduced matter-only Hamiltonian is obtained. Several simplifications using integrations by parts are discussed. Approximate solutions to the constraints and evolution equations of motion are provided. Technical details of the integration procedures are given including an analysis of the short-range behavior of the integrands around the sources. The Hamiltonian of a test-spin moving in a stationary Kerr spacetime is obtained by rather simple approach and used to check parts of the mentioned results. Kinematical consistency checks by using the global (post-Newtonian approximate) Poincaré algebra are applied. Along the way a self-contained overview for the computation of the 3PN ADM point-mass Hamiltonian is provided, too.
