标题： Topological symmetry-restored phase of gravity

摘要： 在这项工作中，我们提出了一种四维引力的拓扑量子场论相。我们证明它不仅能生成广义相对论，还能生成整个Lovelock-Cartan引力理论族。这是由于存在一种拓扑对称性，当通过引入质量尺度显式破缺时，会释放引力的局域自由度。此外，我们引入了(反)自对偶Landau规范条件的扩展概念，以评估Ward恒等式、反项，并利用代数重整化技术证明该模型在微扰论的所有阶次下的量子稳定性。 显示英文摘要

摘要： In this work, we propose a topological quantum field theory phase for four-dimensional gravity. We show it is able to generate, not only General Relativity, but the whole family of Lovelock-Cartan theories of gravity. This is accomplished due to the existence of a topological symmetry which, when explicitly broken via the introduction of a mass scale, releases the local degrees of freedom of gravity. Additionally, we introduce an extended notion of the (anti-)self-dual Landau gauge conditions to evaluate the Ward identities, counterterms, and prove the quantum stability of the model, to all orders in perturbation theory, using the algebraic renormalization technique.
