Hawking radiation of Euler-Heisenberg-adS black hole under the GUP effect

We study Hawking radiation produced by charged Klein-Gordon and Dirac particles as tunneling from the event horizon of the Euler-Heisenberg-anti de Sitter black hole in the presence of a generalized uncertainty effect. To obtain modified Hawking temperature we use semi-classical versions of charged Klein-Gordon and Dirac equations. We review the general properties of the black hole and its standard thermodynamics elaborately. We discuss the problem of the formation of a residual mass at a finite temperature that arises in this black hole where the volume shrinking terminates even if the Hawking radiation continues at a constant rate. We find that the first-order correction of the generalized uncertainty principle to the Klein-Gordon and Dirac equations cannot be able to solve this problem. Apart from this fact, we interpret the modified thermodynamics of the black hole from another point of view under the generalized uncertainty principle effect. We model the charge/mass ratio Q/M ? [0.612, 0.729] and then calculate the standard critical Hawking temperature of Sgr A* T-H ? [27, 24] fK for the Euler-Heisenberg parameter a/Q(2) ? [0, 32/7]. Improved upper limits under the GUP corrections are Q/M = 0.769, T-K G = 406 fK for the KG particle and Q/M = 0.777, T-D = 410 fK for the Dirac particle.
