摘要

在本研究中,我们在f(R,Lm,T)引力的框架内,利用MIT袋态方程,探索了奇异夸克物质支持的可穿越虫洞的存在性。考虑f(R,Lm,T)模型的三种不同的函数形式,并采用两种具有对数红移函数的特定形状函数来分析虫洞解。研究了半径为0的虫洞咽喉处的能量条件,以评估β、γ1和γ2参数对能量条件,特别是零能条件的破坏的影响。此外,利用Tolman-Oppenheimer-Volkoff (TOV)方程进行了稳定性分析,证实了得到的虫洞解的稳定性。最后,我们研究虫洞的有效引力质量,以进一步了解其物理可行性。我们已经得出结论,我们的虫洞解决方案是稳定的和可穿越的,由于重力的改变而违反了NEC。尽管存在外来物质,虫洞仍保持着积极的活动质量,类似于普通物质的引力影响。我们的发现有助于更广泛地理解扩展引力理论中的虫洞解及其天体物理学含义。

A study of wormhole solution using MIT bag parameter B in the framework of f(R,Lm,T) gravity
In this study, we explore the existence of traversable wormholes supported by strange quark matter, modeled using the MIT bag equation of state, within the framework of f(R,Lm,T) gravity. We analyze wormhole solutions considering three distinct functional forms of the f(R,Lm,T) model and adopting two specific shape functions with a logarithmic redshift function. The energy conditions at the throat of the wormhole, located at radius r0, are examined to assess the influence of the parameters β, γ1 and γ2 on the violations of the energy conditions, particularly the null energy condition. Furthermore, a stability analysis was performed using the Tolman–Oppenheimer–Volkoff (TOV) equation, which confirmed the stability of the obtained wormhole solutions. Lastly, we investigate the active gravitational mass of the wormhole to gain further insight into its physical viability. We have concluded that our wormhole solutions are stable and traversable, with NEC violation due to modified gravity. Despite exotic matter, the wormhole maintains a positive active mass, resembling the gravitational influence of ordinary matter. Our findings contribute to the broader understanding of wormhole solutions in extended theories of gravity and their astrophysical implications.
