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…

Parametric Solution of a Small-Large Black Hole Coexistence Curve
Shanshan Li, Dan-Dan Li, Li-Qin Mi +1
We consider the first-order phase transition of a charged anti-de Sitter black hole, and find that the equation of state with the conditions of the two coexisting phases, leads to…
