摘要

We derive Hawking radiation of five-dimensional black rings from gauge and gravitational anomalies using the method proposed by Robinson and Wilczek. We find, as in the black hole case, that the problem could reduce to a ( 1+1)- dimensional field theory and the anomalies result in correct Hawking temperature for neutral, dipole and charged black rings.

Probability distribution for black hole evaporation

Pratik Ghosal, Rajarshi Ray

Summary: The nonthermal correction to the emission probability of particles from black holes is significant as it helps determine the probability of complete black hole evaporation and matches the initial entropy of the black hole. The study reveals that this probability distribution resembles Wien's displacement law for blackbody radiation.

Acoustic black and white holes of potential flow in a tube

Ren Tsuda, Shinya Tomizawa, Ryotaku Suzuki

Summary: We propose a new simple model of an acoustic black hole in a thin tube by utilizing the difference in gravitational potential to generate transonic flow. The analytical solution for the Euler equations can be obtained in our transonic flow model, providing an exact solution in terms of a height function for the monatomic case with gamma 1/4 5/3. By the near-sonic approximation, we find a simple form for arbitrary gamma. Additionally, two analytic solutions describing a backward wave and a forward wave are obtained, demonstrating the existence of sonic horizons.

GW190521: Search for echoes due to stimulated Hawking radiation from black holes

Jahed Abedi, Luis Felipe Longo Micchi, Niayesh Afshordi

Summary: GW190521 is the most massive binary black hole merger event observed so far, and it is of special interest. We conducted a comprehensive search for gravitational wave echoes using two independent methods and found a possible signal. Although the current evidence does not meet the gold standard of 5 sigma, our findings are consistent with predictions and the next generation of gravitational wave observatories can provide a definitive conclusion on the quantum nature of black hole horizons.

Baryogenesis through asymmetric Hawking radiation from primordial black holes as dark matter

Alexis Boudon, Benjamin Bose, Hyat Huang, Lucas Lombriser

Summary: This study investigates the potential of primordial black holes (PBHs) to serve as observed dark matter, contribute to matter-antimatter asymmetry, and account for baryon abundance. It is found that correct energy densities for dark matter and baryons can be achieved under different mass spectra, while measured baryon asymmetry can be recovered to within an order of magnitude. Further research is warranted based on these initial findings.

Separating the superradiant emission from the Hawking radiation from a rotating black hole

De-Chang Dai, Dejan Stojkovic

Summary: The emission of particles from a rotating black hole can be significantly boosted, leading to the extraction of rotational energy. This phenomenon, known as superradiance, affects both particles created near the black hole's horizon and those created near the potential barrier far from the horizon. We provide explicit calculations of superradiant emission for scalar particles and differentiate it from the total particle emission (combining Hawking radiation and superradiance), resolving confusion in the literature. Furthermore, we demonstrate that superradiance persists even for extremal black holes with zero Hawking temperature.

Thermal behavior of a radially deformed black hole spacetime

Subhajit Barman, Sajal Mukherjee

Summary: This article examines the Hawking effect and bounds on greybody factor in a spacetime with radial deformation, showing that the deformation parameter enhances both temperature and bounds. The radial deformation introduces changes in the location of the horizon, affecting the thermal behavior and creating a useful distinction with Kerr spacetime. Moreover, the separation of scalar field equation in terms of angular and radial coordinates facilitates the study of the Hawking effect and greybody factors.

Joule-Thomson expansion of lower-dimensional black holes

Jing Liang, Benrong Mu, Peng Wang

Summary: In this study, the Joule-Thomson expansion is extended to the low-dimensional regime by considering the rotating BTZ metric in (2 + 1)-dimensional space-time. The properties of Joule-Thomson coefficient, inversion curve, and isenthalpic curve were investigated, along with the divergence and zero points. The minimum inversion temperature was found to be zero, leading to the black hole becoming an extremal black hole, with no critical behavior exhibited in BTZ black holes.

Lorentz-breaking theory and tunneling radiation correction to Vaidya-Bonner de Sitter Black Hole

Bei Sha, Zhi-E Liu

Summary: In this study, the tunneling radiation characteristics of fermions and bosons in Vaidya-Bonner de Sitter black hole space-time were corrected by considering Lorentz symmetry breaking theory. The new modified forms of Dirac equation for fermions with spin 1/2 and Klein-Gordon equation for bosons in the curved space-time of the black hole were obtained. Through solving these equations, new and corrected expressions for surface gravity, Hawking temperature, and tunneling rate of the black hole were obtained and discussed.

The gravitational bending of acoustic Schwarzschild black hole

Chen-Kai Qiao, Mi Zhou

Summary: This study investigates the gravitational bending of acoustic Schwarzschild black hole and carefully analyzes the gravitational deflection angle of particles, weak gravitational lensing, and Einstein ring. The results show that gravitational bending effect is enhanced in acoustic Schwarzschild black hole compared to conventional Schwarzschild black hole, indicating that acoustic black holes may be more easily detectable in gravitational bending effects and weak gravitational lensing observations.

New accretion constraint on the evaporation of primordial black holes

Seyed Sajad Tabasi, Mahsa Berahman, Javad T. Firouzjaee

Summary: In this paper, we investigate the processes of evaporation and accretion of primordial black holes during different eras. Previous studies considered these processes to be independent, but our calculations show that assuming they are independent leads to incorrect results. We also demonstrate that considering the dynamic event horizon can lead to the shutdown of the Hawking evaporation process. This study provides a more accurate and detailed understanding of the mass evolution of primordial black holes.

Quasibound states of Schwarzschild acoustic black holes

H. S. Vieira, Kostas D. Kokkotas

Summary: This paper investigates the Schwarzschild acoustic black hole spacetime, exploring physical phenomena related to its effective geometry such as analogous Hawking radiation and quasibound states. By calculating quasibound state frequencies and wave functions, and comparing them with standard Schwarzschild black hole frequencies, the study provides insights into black hole physics and analog models in condensed matter, potentially offering the possibility of laboratory testing for effects associated with purely quantum effects in gravity.

Oscillatory states of quantum Kapitza pendulum

Wei He, Chang -Yong Liu

Summary: We study the quantum mechanics problem described by the Schrodinger equation with the Kapitza pendulum potential, which is an asymmetric double-well potential on the circle. We obtain the perturbative eigenvalues and corresponding piecewise wavefunctions for the oscillatory states localized around the two stable saddle positions of the potential. The spectrum is computed by extending the angle coordinate to the complex plane and formulating the quantization condition as a contour integral along an imaginary path. Quantum tunneling between the wells is also computed.
