Abstract

The possibility of static and spherically symmetric traversable wormhole solution in modified teleparallel Rastall gravity in a non-diagonal tetrad is investigated. Rastall assumption modifies the field equations and energy-momentum conservation law. These modifications lead to different exact asymptotically flat traversable wormhole solutions. By imposing different constraints on modified energy-momentum conservation law, different exact solutions are found and the obtained results for teleparallel Rastall gravity, with specific choices of f(T), are studied. It is shown that the Rastall parameters have a key role in these model and in all of those exact traversable wormhole solutions the null energy condition and weak energy condition of matter or energy which has surrounded the wormhole are valid at the throat of the wormhole and through the space time as well.

修正遥平行时空重力和能量条件下的虫洞解
研究了非对角四分体中修正遥平行拉斯特引力条件下静态和球对称可穿越虫洞解的可能性。拉斯托假设修正了场方程和能量动量守恒定律。这些修正导致了不同的精确的渐近平坦可穿越虫洞解。通过对修正的能量动量守恒定律施加不同的约束,得到了远平行拉斯托引力的不同精确解,并对f(T)的具体选择进行了研究。结果表明,Rastall参数在这些模型中起着关键作用,并且在所有这些精确的可穿越虫洞解中,包围虫洞的物质或能量的零能条件和弱能条件在虫洞的咽喉处和时空中都是有效的。
