我们在具有大扭矩的庞加莱规范场论框架中找到了一种新的精确真空解。在此模型中，挠率作为独立场运行，并对广义相对论中的真空结构进行修正。新的静态球对称构型显示了以自旋电荷为特征的类赖斯纳-诺德斯特伦几何结构。它将已知的无质量扭转解决方案扩展到大型案例。相应的 Reissner-Nordström-de Sitter 解也与宇宙常数和附加 U (1) 规范场兼容。
We find a new exact vacuum solution in the framework of the Poincaré Gauge field theory with massive torsion. In this model, torsion operates as an independent field and introduces corrections to the vacuum structure present in General Relativity. The new static and spherically symmetric configuration shows a Reissner–Nordström-like geometry characterized by a spin charge. It extends the known massless torsion solution to the massive case. The corresponding Reissner–Nordström–de Sitter solution is also compatible with a cosmological constant and additional U (1) gauge fields.
