Thermodynamics of Ideal Gas in Doubly Special Relativity
arXiv:1108.0896 · doi:10.1103/PhysRevD.85.045012
Abstract
We study thermodynamics of an ideal gas in Doubly Special Relativity. New type of special functions (which we call Incomplete Modified Bessel functions) emerge. We obtain a series solution for the partition function and derive thermodynamic quantities. We observe that DSR thermodynamics is non-perturbative in the SR and massless limits. A stiffer equation of state is found.
