TL;DR: The superspace analogue of the improved energy-momentum tensor is analyzed in this article, where the supercurrent of Ferrara and Zumino is derived from the superspace translation tensor in its minimal form.

TL;DR: In this paper, a new exact solution to the Einstein-Cartan theory is presented, recast in the standard form of Einstein's theory with the introduction of an effective energy-momentum tensor.

TL;DR: In this article, the path-dependent Lagrangian is used to derive the energy-momentum tensor of the electromagnetic field and a system of bound charges, and the Poisson brackets for the field are defined in a consistent way.
Abstract: The path-dependent Lagrangian is used to derive the energy-momentum tensor of the electromagnetic field and a system of bound charges. The Poisson brackets for the field are defined in a consistent way. Momentum is defined for both field and matter. The Hamiltonian of the combined system is given. The whole description is without any reference to electromagnetic potentials.

TL;DR: In this article, the authors derived a general expression of the conformally covariant energy-momentum tensor by starting from the general form of the Lagrangian from which the field equations are conformal covariant.
Abstract: Derives a general expression of the conformally covariant energy-momentum tensor by starting from the general form of the Lagrangian from which the field equations are conformally covariant. The conformal group consists of inhomogeneous Lorentz transformations, dilatation transformations, and special conformal transformations.

TL;DR: In this paper, a conformal covariant energy-momentum tensor tensor is proposed in terms of which other conformal currents are expressed, and the conformal symmetric theory is considered.
Abstract: In a conformal symmetric theory the author proposes a conformal covariant energy-momentum tensor, in terms of which other conformal currents are expressed.
