摘要

本研究在f(Q,T)引力理论框架内，结合保角对称性，提出了新颖且物理上可行的虫洞解决方案。研究考虑了无迹、各向异性和各向压状态方程，探索了在不同情况下可穿越虫洞的可行性。此外，还深入研究了模型参数对这些虫洞结构的存在和特征的影响。值得注意的是，得出的形状函数满足所有必要的标准。此外，在其中一种情况下，确认了非外来流体的存在，而在其他情况下，只需要在虫洞喉部附近存在外来物质。

Probing the existence of wormhole solutions in f(Q,T) gravity with conformal symmetry

This study presents novel and physically plausible wormhole solutions within the framework of $f (Q, T)$ gravity theory, incorporating conformal symmetries. The investigation explores the feasibility of traversable wormholes under diverse scenarios, considering traceless, anisotropic, and barotropic equations of state. Additionally, the influence of model parameters on the existence and characteristics of these wormhole structures is thoroughly examined. Notably, the derived shape function satisfies all the necessary criteria. Furthermore, in one of the cases, the presence of non-exotic fluid is confirmed, while in others, exotic matter is only required near the wormhole throat.
