Comment on "Quantum Tunneling Beyond Semiclassical Approximation" by R. Banerjee and B. R. Majhi (and many others!)

We discuss recent work which has found, using a tunneling approach, higher-order terms in the Hawking temperature. We highlight a few important issues in the derivation, such as a misleading definition of energy, and criticize some of the conclusions that have been reached. In particular, we conclude that contrary to many recent claims, the tunneling method yields no higher-order corrections to the Hawking Temperature.
