The Energy-Momentum Tensor for Gravitational Interactions
Within the Lagrange formalism we show that the gauge invariant total energy-momentum tensor for gravitational interactions is zero. If the equations of motion are satisfied the energy tensor is conserved.
متن کاملHard Thermal Loops, Weak Gravitational Fields and The Quark Gluon Plasma Energy Momentum Tensor
We use an auxiliary field construction to discuss the hard thermal loop effective action associated with massless thermal SU(N) QCD interacting with a weak gravitational field. It is demonstrated that the previous attempt to derive this effective action has only been partially successful and that it is presently only known to first order in the graviton coupling constant. This is still sufficie...
متن کاملThe Energy-momentum Tensor for the Gravitational Field
The search for the gravitational energy-momentum tensor is often qualified as an attempt of looking for “the right answer to the wrong question”. This position does not seem convincing to us. We think that we have found the right answer to the properly formulated question. We have further developed the field theoretical formulation of the general relativity which treats gravity as a non-linear ...
متن کاملRenormalized stress-energy tensor for spin-1/2 fields in expanding universes
We provide an explicit expression for the renormalized expectation value of the stressenergy tensor of a spin-1/2 field in a spatially flat Fridmann-Lemaitre-Robertson-Walker universe. Its computation is based on the extension of the adiabatic regularization method to fermion fields introduced recently in the literature. The tensor is given in terms of UV-finite integrals in momentum space, whi...
متن کاملOn Tensorial Concomitants and the Non-Existence of a Gravitational Stress-Energy Tensor†
Based on an analysis of what it may mean for one tensor to depend in the proper way on another, I prove that, under certain natural conditions, there can be no tensor whose interpretation could be that it represents gravitational stress-energy in general relativity. It follows that gravitational energy, such as it is in general relativity, is necessarily nonlocal. Along the way, I prove a resul...
