Thoughts on entropic gravity in the Parikh-Wilczek tunneling model of Hawking radiation
arXiv:1312.1815 · doi:10.1140/epjc/s10052-014-2912-5
Abstract
In this letter, we use the Parikh-Wilczek tunneling model of Hawking radiation to illustrate that a reformulation of Verlinde's entropic gravity is needed to derive the Newton's law for a temperature-varying screen, demanded by the conservation of energy. Furthermore, the entropy stored in the holographic screen is shown to be additive and its temperature dependence can be obtained.
