Entropic forces in a Kerr geometry: A link with rotational properties
2011Citations per year
Abstract: (IOP)
The recent thermodynamical interpretation of the field equations of gravity is revisited and extended to the killing horizons linked to the rotation (Kerr black holes). An entropic force can be defined also for these horizons which are not event h orizons but show thermodynamical features that in previous works were used to explain the rotational properties of Kerr solutions. Such entropic force is needed to describe the energetic processes, which do not change the usual thermal entropy of the rota ting black hole (reversible transformations, superradiance).- force: entropy
