Analysis of Stress-Energy Tensor and Conservation in Classical and Quantum Physics: Concepts and Applications

The analysis of the stress-energy tensor and conservation in classical and quantum physics plays a vital role in understanding the relationship between energy, momentum, and the structure of spacetime. This tensor is recognized as one of the fundamental tools in classical and quantum field theories, with wide applications in modeling various physical systems. The aim of this study is to provide a comprehensive review of the stress-energy tensor and conservation in both classical and quantum contexts. In this research, articles from reputable databases such as Google Scholar, Scopus, and ScienceNet were searched and reviewed from ۲۰۲۱ to ۲۰۲۵. A total of ۶۰۰ initial papers were reviewed, and after applying inclusion and exclusion criteria, ۱۰ papers were selected for the final study. The selection criteria included direct relevance to the stress-energy tensor and conservation in classical and quantum physics, with a focus on quantum corrections and gravitational effects in cosmological models. The results of this study indicate that the stress-energy tensor contributes to a more accurate modeling of spacetime and gravity. Furthermore, quantum corrections assist in enhancing gravitational simulations and cosmological analyses. These findings can aid in advancing research and more complex models in theoretical and quantum physics.The analysis of the stress-energy tensor and conservation in classical and quantum physics plays a vital role in understanding the relationship between energy, momentum, and the structure of spacetime.
