Entropy of 2+1 de Sitter space with the GUP
Wontae Kim, Yong-Wan Kim, Young-Jai Park
Abstract
By introducing the generalized uncertainty principle (GUP) on the quantum state density, we calculate the statistical entropy of a scalar field on the background of (2+1)-dimensional de Sitter space without artificial cutoff. The desired entropy proportional to the horizon perimeter is obtained.
