论文摘要
我们在Horndeski重力理论的偏移对称扇区中提出了不同的Taub-nut/Bolt-anti de Sitter（ADS）溶液，该理论具有标量场与爱因斯坦张量的非微动力学偶联。在四个维度中，我们在局部和渐近地在局部广告中找到具有非平凡标量场的解决方案。在较高的维度中，获得了分析性的taub-nut/螺栓ads p-branes和soliton，并由具有轴子谱的P Horndeski标量场的存在支持。通过欧几里得方法研究了热力学特性，并发现满足了热力学的第一定律。此外，通过要求质量，熵和p-branes和soliton的特定热量的阳性，获得了Horndeski重力和螺母电荷参数空间的约束。我们简要评论了全息应用中的未来应用。
We present different Taub-NUT/Bolt-anti de Sitter (AdS) solutions in a shift-symmetric sector of Horndeski theory of gravity possessing nonminimal kinetic coupling of scalar fields to the Einstein tensor. In four dimensions, we find locally and asymptotically locally AdS solutions possessing nontrivial scalar field. In higher dimensions, analytical Taub-NUT/Bolt-AdS p-branes and solitons are obtained, supported by the existence of p Horndeski scalar fields with axionic profile. The thermodynamical properties are studied through Euclidean methods and it is found that the first law of thermodynamics is satisfied. Moreover, constraints on the parameter space of Horndeski gravity and NUT charge are obtained by demanding positivity of the mass, entropy, and specific heat of the p-branes and soliton. We briefly comment on future applications in holography.
