摘要

在本文中,我们通过在修正的f(R;T)重力理论。我们取两个不同的f1(R)模型,f1(R) = R􀀀(1􀀀e􀀀R)称为指数重力模型,f1(R) = R􀀀tanh(R)称为Tsujikawa模型,其中;是模型参数。我们探索了这些模型的可行解。此外,我们通过给出合适的模型参数值,分析和图解地讨论了这些虫洞模型的不同性质。我们考虑一个特定的形状函数,即b(r) = r0 log(rr0 + 1),并讨论了上述两种模型的能量条件。最后,我们发现所得到的虫洞解在物理上是可以接受的,与所考虑的指数和Tsujikawa重力模型有或没有外来物质的存在。

Wormhole solutions and energy conditions in f(R; T) gravity with exponential models
In the present article, we explore the new exact solutions of wormhole geometry by imposing the nonconstant Ricci scalar under inhomogeneous spacetime in the modified f(R; T) theory of gravity. We take two dissimilar models of f1(R) that are f1(R) = R 􀀀 (1 􀀀 e 􀀀R ) known as exponential gravity model and f1(R) = R 􀀀 tanh(R ) known as Tsujikawa model, where; are model parameters. We explore the feasible solutions for these models. Moreover, we discuss analytically and graphically the different properties of these models of wormholes by giving suitable values to the model parameters. We consider a specific shape functions i.e., b(r) = r0 log( r r0 + 1) and discuss the energy conditions for the above mentioned two models. Conclusively, we find that obtained wormhole solutions are physically acceptable with the considered exponential and Tsujikawa gravity models with or without the presence of exotic matter.
