Exact quasinormal modes in Grumiller spacetime
Li-Qin Mi, Zhong-Heng Li
The Grumiller metric is an effective model for gravity at large distances and plays a significant role in constructing galactic models and explaining dark matter. Here, in Grumille…

Quasibound states of massless spin particles in Schwarzschild equivalent mediums
Li-Qin Mi, Dandan Li, Zhong-Heng Li
We show that, in Schwarzschild equivalent mediums, the massless spin particles obey the same dynamical equation, from which we obtain remarkably simple formulae for the frequencies…
