暗物质和暗能量支持下Lorentz对称性破缺下有效薄壳虫洞的稳定性

Stability of Effective Thin-shell Wormholes Under Lorentz Symmetry Breaking Supported by Dark Matter and Dark Energy

Ali Övgün, Kimet Jusufi

摘要:

在本文中,我们构造了一般的球对称薄壳虫洞,并使用统一的暗扇区,包括暗能量和暗物质检查它们的稳定性。我们给出了一个主方程,从它可以恢复,作为一个特殊的情况下,其他稳定性解决方案的一般球对称薄壳虫孔。在这种情况下,我们考虑一个特殊的解决方案,即我们构建一个有效的薄壳层虫洞下洛伦兹对称性破缺。我们探讨了稳定性分析,使用不同的模型的修改后的Chaubergin气体与宇宙学观测,如第七年全威尔金森微波各向异性探测数据点,Ia型超新星,和重子声学振荡的约束。在所有这些模型中,我们找到稳定的解决方案,通过选择合适的值的参数的洛伦兹对称性破缺效应。

英文摘要:

In this paper, we construct generic, spherically symmetric thin-shell wormholes and check their stabilities using the unified dark sector, including dark energy and dark matter. We give a master equation, from which one can recover, as a special case, other stability solutions for generic spherically symmetric thin-shell wormholes. In this context, we consider a particular solution; namely we construct an effective thin-shell wormhole under Lorentz symmetry breaking. We explore stability analyses using different models of the modified Chaplygin gas with constraints from cosmological observations such as seventh-year full Wilkinson microwave anisotropy probe data points, type Ia supernovae, and baryon acoustic oscillation. In all these models we find stable solutions by choosing suitable values for the parameters of the Lorentz symmetry breaking effect.
