"The Alena Tensor is a recently discovered class of stress-energy tensors that, as previous publications have shown, has extremely useful properties. In curved spacetime, this tensor reproduces Einstein Field Equations and in flat Minkowski spacetime, it describes a physical system with fields that can be widely configured. The use of the discussed tensor may significantly simplify Quantum Field Theory equations and it also provides canonical, generalized four-momentum with vanishing four-divergence that satisfies Klein-Gordon equation. This article discusses the perspectives of applications of Alena Tensor in Quantum Field Theory and unification theories against the background of existing research directions." - From the abstract.
