摘要：
We introduce a framework in which classical gravity arises from stress-tensor deformations of quantum field theories (QFTs). By expressing the deformed partition function as a gravitational path integral, we propose an equivalent description between a seed QFT coupled to gravity and an effective field theory defined on a deformation-induced metric. This approach, which does not rely on holography or extra dimensions, applies to a variety of gravitational models, including Einstein and Palatini gravity. The deformation parameter acts as a coupling to the emergent geometry, linking stress-energy dynamics to spacetime curvature. The framework provides a calculable, dimension-independent method for studying gravitational theories resulting from QFT deformations.

Song He is a Professor at the Institute for Fundamental Physics and Quantum Technology, Ningbo University. He received his Ph.D. in 2011 from the Institute of High Energy Physics, Chinese Academy of Sciences, and subsequently held postdoctoral positions at the Institute of Theoretical Physics (CAS), the Yukawa Institute for Theoretical Physics at Kyoto University, and the Max Planck Institute for Gravitational Physics (Albert Einstein Institute). In 2019 he joined the Faculty of Physics at Jilin University as a professor. His research spans gravitational theory, quantum field theory, string theory, and mathematical physics. His current interests focus on uncovering the nature of gravity through dualities between strings and fields, and on using gauge/gravity duality to study nonperturbative phenomena in quantum field theory.
