Abstract
The importance of the Voros product in defining a noncommutative inspired Reissner–Nordström black hole is emphasized. The entropy of this black hole is then computed in the tunneling approach and is shown to obey the area law at the next to leading order in the noncommutative parameter θ. Correspondingly modifications (logarithmic in nature) to entropy/area law is obtained by going beyond the semiclassical approximation. Also the Komar energy is computed and its relation with the entropy and semiclassical Hawking temperature is studied. The coefficient of the logarithmic term is evaluated and involves the noncommutative parameter θ.
