Abstract

In this paper, we explore the physical properties and characteristics of static, spherically symmetric wormholes in the background of Rastall–Rainbow gravity. The Rastall–Rainbow gravity theory has recently been proposed as a combination of two theories, namely, the Rastall theory and the Rainbow description. We implemented noncommutativity by adopting two different distributions of energy density (Gaussian and Lorentzian) in the Morris and Thorne metric. We solve the field equations analytically and discuss all the properties of wormholes depending on the two model parameters. Notably, for specific parameter ranges, one can alleviate the violation of the WEC at the throat and its neighborhood.

拉斯塔尔-彩虹引力中虫洞的非交换效应
本文探讨了在拉斯托尔-彩虹引力背景下静态球对称虫洞的物理特性和特征。最近提出的拉斯托尔-彩虹引力理论是两种理论的结合,即拉斯托尔理论和彩虹描述。我们在莫里斯和索恩公设中采用了两种不同的能量密度分布(高斯分布和洛伦兹分布),从而实现了非交换性。我们对场方程进行了分析求解,并讨论了取决于两个模型参数的虫洞的所有特性。值得注意的是,在特定的参数范围内,我们可以减轻虫洞及其邻近地区的虫洞违反行为。
