Minimal length phenomenology and the black body radiation

Abstract

Abstract The generalized uncertainty principle (GUP) modifies the uncertainty relation between momentum and position giving room for a minimal length, as predicted by candidates theories of quantum gravity. Inspired by GUP, Planck’s distribution is derived by considering a new quantization of the electromagnetic field. We elaborate on the thermodynamics of the black body radiation obtaining Wien’s law and the Stefan–Boltzmann law. We show that such thermodynamics laws are modified at Planck-scale.
