This analysis explores the solutions for wormhole in f(R,φ,χ) gravity, where χ,φ, and R represent the kinetic term, scalar potential, and Ricci scalar, respectively. For this study, we use the spherically symmetric spacetime with the anisotropic source of matter. Further, we use the linear equation of state to complete this current investigation in the background of conformal symmetry motion. By plugging non-zero conformal Killing vectors, we discuss the feasible phantom wormhole configurations. Under the linear equation of state, the stability of wormhole solutions with specific values of parameters is also checked by using the Tolman–Oppenheimer–Volkoff equation. Further, the energy conditions are also discussed with conformal motions. Moreover, it is concluded that our inquired solutions are physically viable in f(R,φ,χ) gravity.

通过 f(R,φ,χ) 重力中的共形对称性可穿越的幻影虫洞

本分析探讨了虫洞的解决方案F(R,φ,χ)重力,在哪里χ,φ, 和R分别代表动力学项、标量势和 Ricci 标量。在这项研究中,我们使用具有各向异性物质源的球对称时空。此外,我们使用线性状态方程在共形对称运动的背景下完成了当前的研究。通过插入非零保形杀死向量,我们讨论了可行的幻影虫洞配置。在线性状态方程下,使用 Tolman-Oppenheimer-Volkoff 方程也可以检验具有特定参数值的虫洞解的稳定性。此外,能量条件也与保形运动一起讨论。此外,我们得出的结论是,我们所研究的解决方案在物理上是可行的F(R,φ,χ)重力。
