Fermions Tunneling from Non-Stationary Dilaton-Maxwell Black Hole via General Tortoise Coordinate Transformation 下载免费PDF全文
Fermions tunneling of the non-stationary Dilaton-Maxwell black hole is investigated with general tortoise coordinate transformation. The Dirac equation is simplified by semiclassical approximation so that the Hamilton-Jacobi equation is generated. Finally the tunneling rate and the Hawking temperature is calculated. 相似文献

Quantum Tunnelling and Hawking Radiation of Schwarzchild-Anti-de Sitter Black Hole with Topological Defect 下载免费PDF全文
We extend Parikh's recent work to Schwarzchild-anti-de Sitter black hole with topological defect whose Arnowitt-Deser-Misner (ADM) mass is no longer identical to its mass parameter. We view the Hawking radiation as a tunnelling process across the event horizon and the cosmological horizon. From the tunnelling probability, we find a leading correction to the semi-classical emission rate. The result employs an underlying unitary theory. 相似文献

By introducing a new tortoise coordinate transformation, we investigate the quantum thermal and non-thermal radiations of a non-stationary Kerr--Newman--de Sitter black hole. The accurate location and
radiate temperature of the event horizon as well as the maximum energy of the non-thermal radiation are derived. It is shown that the radiate temperature and the maximum energy are related to not only the evaporation rate, but also the shape of the event horizon, moreover the maximum energy depends on
the electromagnetic potential. Finally, we use the results to reduce the non-stationary Kerr--Newman black hole, the non-stationary Kerr black hole, the stationary Kerr--Newman--de Sitter black hole, and the static Schwarzshild black hole. 相似文献

The thermal radiation spectrum of a generally non-stationary black hole is studied. The conclusion is discussed in some special cases. The calculation and the discussion show that the thermal radiation spectrum may depend on the angular variables of the black hole. 相似文献

研究了动态Kerr黑洞时空中的粒子能级,计算了最低正能级和最高负能级的精确表达式。在动态Kerr黑洞视界附近的能级交错表明,动态Kerr黑洞的非热辐射的频率范围不仅拖曳角速度有关,而且与黑洞的蒸发率和视界形状也有关。 相似文献
