The geodesics of tunneling particles were derived unnaturally and awkwardly in previous works. For one thing, the previous derivation was inconsistent with the variational principle of action. Moreover, the definition of geodesic equations for massive particles was quite different from that of massless case. Even worse, the relativistic and nonrelativistic foundations were mixed with each other during the past derivation of geodesics. As a highlight, remedying the urgent shortcomings, we improve treatment to derive the geodesic equations of massive and massless particles in a unified and self-consistent way. Besides, we extend to investigate the Hawking radiation via tunneling from Reissner-Nordström black holes in the context of AdS spacetime. Of special interest, the trick of utilizing the first law of black hole thermodynamics manifestly simplifies the calculation of tunneling integration. 相似文献

We investigate the massive vector particles' Hawking radiation from the neutral rotating Anti-de Sitter(AdS) black holes in conformal gravity by using the tunneling method.It is well known that the dynamics of massive vector particles are governed by the Proca field equation.Applying WKB approximation to the Proca equation,the tunneling probabilities and radiation spectrums of the emitted particles are derived.Hawking temperature of the neutral rotating AdS black holes in conformal gravity is recovered,which is consistent with the previous result in the literature. 相似文献

CFT adapted gauge invariant formulation of arbitrary spin fields in AdS and modified de Donder gauge
Using Poincaré parametrization of AdS space, we study totally symmetric arbitrary spin massless fields in AdS space of dimension greater than or equal to four. CFT adapted gauge invariant formulation for such fields is developed. Gauge symmetries are realized similarly to the ones of Stueckelberg formulation of massive fields. We demonstrate that the curvature and radial coordinate contributions to the gauge transformation and Lagrangian of the AdS fields can be expressed in terms of ladder operators. Realization of the global AdS symmetries in the conformal algebra basis is obtained. Modified de Donder gauge leading to simple gauge fixed Lagrangian is found. The modified de Donder gauge leads to decoupled equations of motion which can easily be solved in terms of the Bessel function. Interrelations between our approach to the massless AdS fields and the Stueckelberg approach to massive fields in flat space are discussed. 相似文献

According to Parikh's recent work, Hawking radiation is viewed as a tunneling process and the barrier is created just by the outgoing particle itself. In this paper, we extend Parikh's work to the case of massive particles' tunneling, and calculate the emission rate at which massive particles tunnel across the event horizon of an arbitrarily dimensional Schwarzschild black hole. The result is also consistent with an underlying unitary theory and takes the same functional form as that of massless particles. Moreover, our result also shows that Hawking radiation is an intrinstic property of the black hole. 相似文献

In this study, we consider charged massive scalar fields around a Kerr-Sen spacetime. The radial and angular parts of the covariant Klein-Gordon equation are solved in terms of the confluent Heun function. From the exact radial solution, we obtain the Hawking radiation spectrum and discuss its resonant frequencies. The massless case of the resonant frequencies is also examined. 相似文献

利用Damour-Ruffini方法研究了Reissner-Nordstrom黑洞的Hawking辐射,在考虑辐射能量对背景时空反作用的情况下,发现辐射谱不再是理想的热谱. 得到的修正后的Hawking辐射谱,有可能从黑洞中带出信息,进而用来解释黑洞信息丢失佯谬问题,同时满足量子理论的幺正性. 这里的讨论不仅适合于无静止质量的粒子,而且适合于有静止质量的粒子;不仅适合于标量粒子,而且适合于Dirac粒子;具有广泛的适用性. 相似文献

The paper deals with anisotropic spherically symmetric Lemaitre-Tolman-Bondi model of the universe bounded by the apparent
horizon. Using Hamilton-Jacobi method for both massive and massless test particles, we are able to show that the temperature
associated with the apparent horizon due to Hawking radiation is the usual Hawking Temperature. Also the usual Lemaitre-Tolman-Bondi
model and the transformed r-gauge Lemaitre-Tolman-Bondi model are shown to be equivalent. Finally, the results of Tunneling
approach agree with the Hamiltonian-Jacobi method. 相似文献

Extending Parikh's semi-classical quantum tunnelling model, this paper has studied
the Hawking radiation of the charged particle via tunnelling from the horizon of the
axisymmetric Sen black hole. Different from the uncharged massless particle, the
geodesics of the charged massive particle tunnelling from the horizon is not
light-like. The derived result supports Parikh's opinion and provides a correct
modification to Hawking strictly thermal spectrum developed by the fixed background
space-time and not considering the energy conservation and the self-gravitation
interaction. 相似文献

We clarify the purely imaginary quasinormal frequencies of a massless scalar perturbation on 3D charged-dilaton black holes.
This case is quite interesting, because the step of the potential appears outside the event horizon, similar to the case of
the electromagnetic perturbations on large Schwarzschild–anti-de Sitter (AdS) black holes. It turns out that the potential-step
type with a massless scalar perturbation provides purely imaginary quasinormal frequencies. 相似文献

A special class of higher curvature theories of gravity, Ricci cubic gravity (RCG), in general d dimensional space-time has been investigated in this paper. We have used two different approaches, the linearized equations of motion and the auxiliary field formalism to study the massive and massless graviton propagating modes of the AdS background. Using the auxiliary field formalism, we have found the renormalized boundary stress tensor to compute the mass of the Schwarzschild–AdS and Lifshitz black holes in RCG theory. 相似文献

Hawking radiation is viewed as a tunnelling process. In this way the
emission rates of massless particles and massive particles tunnelling
across the event horizon of general stationary axisymmetric black
holes are calculated, separately. The emission spectra of these two
different kinds of outgoing particles have the same functional form
and both are consistent with an underlying unitary theory. 相似文献

In this paper, massive particles' Hawking radiation via
tunneling from cosmological horizon of a (3+1)-dimensional de Sitter spacetime
is investigated. According to Parikh's theory, when a particle tunnels
across the cosmological horizon, the effective geometry is Schwarzschild-de
Sitter spacetime. In this effective spacetime, a massive particle can be
treated as a de Broglie S-wave. WKB method is used. The emission spectrum is
obtained, and it takes the same functional form as that of massless particles. 相似文献

We use the tunneling formalism to calculate the Hawking radiation of massive particles. For E ≥ m, we recover the traditional result, identical to the massless case. But E < m particles can also tunnel across the horizon in a Hawking process. We study the probability for detecting such E < m particles as a function of the distance from the horizon and the energy of the particle in the tunneling formalism. We derive
a general formula and obtain simple approximations in the near-horizon limit and in the limit of large radii. 相似文献

In this paper, by applying the Lagrangian analysis on the action, we first redefine the geodesic equation of the charged massive particle. Then, basing on the new definition of the geodesic equation, we revisit the Hawking radiation of the charged massive particle via tunneling from the event horizon of the Kaluza-Klein black hole. In our treatment, the geodesic equation of the charged massive particle is defined uniformly with that of the massless particle, which overcomes the shortcomings of its previous definition, and is more suitable for the tunneling mechanism. The highlight of our work is a new and important development for the Parikh-Wilczek’s tunneling method. 相似文献

We apply the confluent Heun functions to study the resonant frequencies (quasispectrum), the Hawking radiation and the scattering process of scalar waves, in a class of spacetimes, namely, the ones generated by a Kerr–Newman–Kasuya spacetime (dyon black hole) and a Reissner–Nordström black hole surrounded by a magnetic field (Ernst spacetime). In both spacetimes, the solutions for the angular and radial parts of the corresponding Klein–Gordon equations are obtained exactly, for massive and massless fields, respectively. The special cases of Kerr and Schwarzschild black holes are analyzed and the solutions obtained, as well as in the case of a Schwarzschild black hole surrounded by a magnetic field. In all these special situations, the resonant frequencies, Hawking radiation and scattering are studied. 相似文献

Since Parikh and Wilczek proposed a semiclassical tunneling method to investigate the Hawking radiation of static and spherically symmetric black holes, the method has been extensively developed to study various black holes. However, in almost all of the subsequent papers, there exists a important shortcoming that the geodesic equation of the massive particle is defined inconsistently with that of the massless particle. In this paper, we propose a new idea to reinvestigate the tunneling radiation from the event horizon of the Reissner-Nordström black hole. In our treatment, by starting from the Lagrangian analysis on the action, we redefine the geodesic equation of the massive and massless particle via tunneling from the event horizon of the Reissner-Nordström black hole, which overcomes the shortcoming mentioned above. The highlight of our work is a new and important development for the Parikh-Wilczek’s semiclassical tunneling method. 相似文献

By calculating the change of entropy, we prove that the first law of black hole thermodynamics leads to the tunneling probability of massive particles through the horizon, including the tunneling probability of massive charged particles from the Reissner–Nordström black hole and the Kerr–Newman black hole. Novelly, we find the trajectories of massive particles are close to that of massless particles near the horizon, although the trajectories of massive charged particles may be affected by electromagnetic forces. We show that Hawking radiation as massive particles tunneling does not lead to violation of the weak cosmic-censorship conjecture. 相似文献

In this paper, we start from the Lagrangian analysis on the action to naturally produce the geodesic equation of the massive particle via tunneling. Then, basing on the new definition for the geodesic equation, we revisit the Hawking radiation of the charged massive particle via tunneling from the Reissner-Nordström-de Sitter black hole with a global monopole. In our treatment, the geodesic equation of the charged massive particle is defined uniformly with that of the massless particle, which overcomes the shortcomings of its previous definition, and is more suitable for the tunneling mechanism. It is noteworthy that, the highlight of our work is a new and important development of the Parikh-Wilczek’s tunneling method. 相似文献
