“…Then, we have studied the greybody factor problem of the RLDBH in order to explore which waves can propagate from the horizon to the spatial infinity. While doing this computation, the lack of the inverse transformation of the confluent Heun functions which is essential to find the exact asymptotic form of the radial solution has enforced us to consider the case of chargeless and massless scalar fields, which was previously considered in [24,70,71,73]. Using a particular transformation between the confluent Heun and hypergeometric functions, we have expressed the radial solution in terms of the hypergeometric functions which posses a broad spectrum of linear transformation features [103].…”

“…The experiments [64][65][66][67] on dilaton and axion fields that naturally exist in the RLDBH geometry may vindicate the dark matter in the near future. At the present time, the studies for the RLDBH [68][69][70][71][72][73][74] in the literature are relatively less than the studies that exist for static linear dilaton black holes [74][75][76][77][78][79][80][81]. In particular, for the problems of absorption cross-section and decay rate for the massless and chargeless bosons emitted by a RLDBH, the reader is referred to [73].…”

Charged massive scalar fields are studied in the gravitational, electromagnetic, dilaton, and axion fields of rotating linear dilaton black holes. In this geometry, we separate the covariant Klein-Gordon equation into radial and angular parts and obtain the exact solutions of both the equations in terms of the confluent Heun functions. Using the radial solution, we study the problems of resonant frequencies, entropy/area quantization, and greybody factor. We also analyze the behavior of the wave solutions near the event horizon of the rotating linear dilaton black hole and derive its Hawking temperature via the Damour-Ruffini-Sannan method.

We investigate the Hawking radiation of massive spin-1 vector particles, which are 9 coupled to vacuum fluctuations of a quantum field, from Rindler modified Schwarzschild black hole. 10 Rindler acceleration is used to produce the post-general relativistic theory of gravity for the distant 11 field of a point mass. The gravitational lensing problem of the Rindler modified Schwarzschild 12 black hole is also studied. We compute the deflection angle for the IR region (large distance limit as 13 infrared ) by using the Gaussian curvature of the optical metric of this back hole. Our investigations 14 clarify how the Rindler acceleration plays a role on the Hawking radiation and gravitational lensing. 15 16 p-1 arXiv:1702.04636v2 [physics.gen-ph] 9 Aug 2017 Sakalli et al.the correlations between the HR and the background geometry [9]. It is worth noting that 38 correlations account for the information stored in the BH with the collapsing matter. Since 39 the original studies of BH emission [1, 2], works on the HR have been still continuing. To 40 date, HR was verified by various methods for many different types of particles having spin 41 s = 0, 1/2, 1, 3/2, 2, ... [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][89][90][91][92]. HR studies include the lower and higher dimensional 42 BHs, wormholes, and black strings [25, 26,[29][30][31][32][33][34]. Recent studies [35][36][37] have claimed that 43 HR has been observed in the laboratory environment. Those experiments about HR were 44 conducted by Steinhauer, who used a sonic (or the so-called analogue) BH in an atomic 45 Bose-Einstein condensate [38] so that a state, where gas bosons are cooled to temperatures 46 very close to absolute zero (that is, very near 0K or −273.16 • C). Thus, the sonic BH 47 could mimic a real cosmic event horizon. At this stage, Steinhauer managed to observe the 48 particles of sound (phonons) at the BH's event horizon and found that sound waves in the 49 Bose-Einstein condensate obey Hawking's theory [37]. However, many physicists are still 50 cautious about these results. Other experiments are needed to support the experiment of 51 Steinhauer.52 In particle physics, spin-1 particles are called vector particles. The most well-known 53 massive spin-1 particles, which are described by a three-dimensional spin vector are the weak 54 intermediate vector bosons Z and W ± , and the mesons Υ, J/Ψ, φ, and ρ [39]. Photons 55 are the massless spin-1 particles, which can only be directed parallel or anti-parallel to their 56 direction of motion. Free massive spin-1 fields are governed by the Proca field equation, 57 and massless spin-1 fields are governed by the Maxwell field equation. Compelling evidence 58 suggests that the spin-1 fields are potential dark matter candidates [40-42]. In recent years, 59 HR of the spin-1 particles have attracted considerable interest [43-49]. 60 In this study, we consider the Rindler modified Schwarzchild BH (RMSBH) [50,51], which 61 was initially proposed by Grumiller to explain the mysterious attract...

“…Some current experiments are focused on the relationship between the dark matter and the dilaton and axion fields [57][58][59][60]. Various studies have also focused on the rotating linear dilaton BHs [61][62][63][64][65][66]. In particular, the problem of area quantization (see [67] for the insights of the famous Bekenstein's area conjecture) from boxed quasinormal modes, which are obtained from caged massless scalar clouds, has been recently studied in [65].…”

We investigate the wave dynamics of a charged massive scalar field propagating in a maximally rotating (extremal) linear dilaton black hole geometry. We prove the existence of a discrete and infinite family of resonances describing non-decaying stationary scalar configurations (clouds) enclosing these rapidly rotating black holes. The results obtained signal the potential stationary scalar field distributions (dark matter) around the extremal linear dilaton black holes. In particular, we analytically compute the effective heights of those clouds above the center of the black hole.
