慢旋转Ellis-Bronnikov虫洞的径向微扰(至二阶)

Radial perturbations of Ellis-Bronnikov wormholes in slow rotation up to second order

Bahareh Azad, Jose Luis Blázquez-Salcedo, Fech Scen Khoo, Jutta Kunz

AI总结:

该研究针对慢旋转Ellis-Bronnikov虫洞的l=0径向微扰展开至二阶分析,推导了对称与非对称虫洞的一般情形,发现旋转可削弱静态虫洞的不稳定模式,足够快的旋转或使其实现线性模式稳定。

摘要:

我们研究慢旋转的Ellis-Bronnikov虫洞,考察其l=0的径向微扰,将旋转展开至二阶。我们给出了一般情形下的详细推导,涵盖对称与非对称虫洞。计算表明,静态情形下存在的不稳定模式随旋转增强不稳定性减弱,直至降为零后消失。这说明虫洞解在旋转足够快时可能达到线性模式稳定。

英文摘要:

We consider slowly rotating Ellis-Bronnikov wormholes and investigate their radial perturbations ($\mathrm{l}=0$), expanding up to second order in rotation. We present the detailed derivations in the general case, including symmetric and non-symmetric wormholes. The calculations show that the unstable mode present in the static case becomes less unstable with increasing rotation, until it reaches zero and then disappears. This indicates that wormhole solutions may become linearly mode stable at sufficiently fast rotation.
