Hawking radiation of regular Hayward black hole surrounded by quintessence

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. (paper)
