Abstract

This study aims to investigate the physical properties of wormhole geometry within the context of

f (T, T)

gravity, which serves as a teleparallel formulation of general relativity. We study a linear model,

f (T, T) = α T + β T

, to explore traversable wormholes. A linear equation of state is utilized for radial pressure, leading to a power-law shaped function. It was found that the violation of energy conditions, depends on the

α

and

β

parameters. A diverse array of intriguing wormhole solutions was identified, contingent upon the specific model parameters employed. It is demonstrated that isotropic wormhole solutions cannot be attained within this framework. Additionally, solutions characterized by a variable equation of state parameter are introduced. A comparative analysis of wormhole solutions in the context of

f (T, T)

and curvature-based gravity, specifically

f (R, T)

, is also provided.

f（T，T）重力下的虫洞

本研究旨在研究f（T，T）引力下虫洞几何的物理性质，这是广义相对论的远平行公式。我们研究了一个线性模型f(T，T)=αT+βT来探索可穿越虫洞。径向压力采用线性状态方程，得到幂律形函数。发现能量条件的违反，取决于α和β参数。根据所采用的特定模型参数，确定了各种有趣的虫洞解决方案。结果表明，各向同性虫洞解不能在此框架内得到。此外，还介绍了以变状态参数方程为特征的解。还提供了f（T，T）和基于曲率的重力（特别是f(R，T)）背景下虫洞解的比较分析。
