“…Therefore, it is found that the entropy spectra of the Schwarzschild-dS and new type-dS black holes are equally spaced. In particular, it was found in lots of literatures [29,48,49,50,51,52,53,54,55,56] that the entropies of black holes in diverse gravity theories are quantized with same spacing. Our results are also consistent with the universal property of equidistant entropy spectrum.…”

We investigate the physical properties of the de Sitter spacetime and new type-de Sitter black holes in new massive gravity, a higher derivative gravity theory in three dimensions. We calculate thermodynamic quantities and check that the first law of thermodynamics is satisfied. In particular, we obtain the energies of the de Sitter spacetime and new type-de Sitter black holes from the renormalized Brown-York boundary stress tensor on the Euclidean surfaces at late temporal infinity. We also obtain the quasinormal modes and by using them we find that the entropy spectra are equally spaced via semi-classical quantization.

We studied the thermodynamics and spectroscopy of a 4-dimensional, = 0 Lifshitz black hole ( 0LBH). Using Wald's entropy formula and the Hawking temperature, we derived the quasi-local mass of the 0LBH. Based on the exact solution to the nearhorizon Schrödinger-like equation (SLE) of the massive scalar waves, we computed the quasi-normal modes of the 0LBH via employing the adiabatic invariant quantity for the 0LBH. This study shows that the entropy and area spectra of the 0LBH are equally spaced.

In this work, the Dirac equation is studied in the [Formula: see text] Lifshitz black hole ([Formula: see text]LBH) spacetime. The set of equations representing the Dirac equation in the Newman–Penrose (NP) formalism is decoupled into a radial set and an angular set. The separation constant is obtained with the aid of the spin weighted spheroidal harmonics. The radial set of equations, which are independent of mass, is reduced to Zerilli equations (ZEs) with their associated potentials. In the near horizon (NH) region, these equations are solved in terms of the Bessel functions of the first and second kinds arising from the fermionic perturbation on the background geometry. For computing the boxed quasinormal modes (BQNMs) instead of the ordinary quasinormal modes (QNMs), we first impose the purely ingoing wave condition at the event horizon. Then, Dirichlet boundary condition (DBC) and Newmann boundary condition (NBC) are applied in order to get the resonance conditions. For solving the resonance conditions, we follow the Hod’s iteration method. Finally, Maggiore’s method (MM) is employed to derive the entropy/area spectra of the [Formula: see text]LBH which are shown to be equidistant.
