We investigate Hawking radiation of regular Hayward black hole surrounded by quintessence. Using the null geodesic method, we derive the expression of the emission rate and deduce the expression of the Boltzmann factor of the black hole. The expression of the change of entropy is also derived using the first law of black hole thermodynamics. The results show that the Boltzmann factor increases when increasing the density of quintessence a or the correction term due to the quantum effects β respectively; showing that the black hole radiates at slower rate. Moreover, the increase of the quantum effects accentuates the decreasing of the change of Bekenstein-Hawking entropy of black hole.

普通海沃德黑洞的霍金辐射被典型包围

我们研究了被典型包围的常规海沃德黑洞的霍金辐射。使用零地线法,我们得出了发射速率的表达式,并推导出了黑洞的玻尔兹曼因子的表达式。熵变化的表达式也使用黑洞热力学第一定律推导。结果表明,随着量子效应β的增加,当增加典型度a或校正项的密度时,玻尔兹曼因子增加;表明黑洞的辐射速度较慢。此外,量子效应的增加加剧了黑洞的Bekenstein-Hawking熵变化的减小。
