Hence the non-relativistic wavefunctions are hydrogenic, and the energy levels are given by (32). University for the continued use of their computing facilities.…”

We investigate the instability of the massive scalar field in the vicinity of a rotating black hole.The instability arises from amplification caused by the classical superradiance effect. The instability affects bound states: solutions to the massive Klein-Gordon equation which tend to zero at infinity.We calculate the spectrum of bound state frequencies on the Kerr background using a continued fraction method, adapted from studies of quasinormal modes. We demonstrate that the instability is most significant for the l = 1, m = 1 state, for M µ 0.5. For a fast rotating hole (a = 0.99) we find a maximum growth rate of τ −1 ≈ 1.5 × 10 −7 (GM/c 3 ) −1 , at M µ ≈ 0.42. The physical implications are discussed. * Electronic address: sam.dolan@ucd.ie

“…Therefore, it is of interest to consider so-called the graviatom of the positronium type, which is a bound state of pairs of particles of dark matter, taking into account only the gravitational interaction. The definition of the graviatom was proposed M. L. Fil'chenkov in [8]. Such graviatoms were formed in the early universe at the birth of pairs and can be preserved until the present era.…”

Abstract. The nature of dark matter in modern physics is an important problem. Therefore, in this paper we consider a quantum system consisting of two identical particles. These particles are candidates for the role of dark matter. We will call them graviatoms and they could be formed in the early Universe. In this paper we have found the energy spectrum of the gravitatom from particles of dark matter, the Bohr radius, the intensity of gravitational radiation, the frequency of radiation, and the lifetime of a state. This lifetime is great for superheavy particles. Estimates of these values for different values of the masses of particles of dark matter are given.

“…It was shown that in this case the DeWitt self-force always exceeds the nonconservative radiation damping force; the energy spectrum and intensity of the electric dipole radiation were calculated for the case of black hole with masses ranging from 10 −5 g to 10 14 g [13] (see also [15]). The conditions of existence of a gravitationally bound quantum system with a neutral black hole as a nucleus were formulated in [16,17] where it was called graviatom.…”

We present a graviatom with de Sitter interior as a new candidate to atomic dark matter generically related to a vacuum dark energy through its de Sitter vacuum interior. It is a gravitationally bound quantum system consisting of a nucleus represented by a regular primordial black hole (RPBH), its remnant or gravitational vacuum soliton G-lump, and a charged particle. We estimate probability of formation of RPBHs and G-lumps in the early Universe and evaluate energy spectrum and electromagnetic radiation of graviatom which can in principle bear information about a fundamental symmetry scale responsible for de Sitter interior and serve as its observational signatures.
