具有变形Heisenberg代数的光子气体的热效应

Thermal effects of a photon gas with a deformed Heisenberg algebra

R. Bufalo

摘要:

本文从广义不确定原理(GUP)的协变推广出发,研究了存在最小可测长度的光子气体的热力学。在一致地建立了广义动力学之后,我们定义了一个GUP变形的Maxwell不变量,作为我们研究的基础。为了突出的GUP效应,我们计算的一个和两个循环的顺序贡献的配分函数在高温极限。然后,通过计算内能密度,我们得出结论,附加项可以看作是由于GUP效应对Stefan-Boltzmann定律的修正$δσ_{\rm{gup}}$。

英文摘要:

In this paper we have consider the thermodynamics of a photon gas subject to the presence of a minimal measurable length following from a covariant extension of the original generalized uncertainty principle (GUP). After establishing consistently a generalized dynamics, we define a GUP deformed Maxwell invariant which serves as the basis for our study. In order to highlight the GUP effects we compute the one- and two-loop order contribution to the partition function at the high-temperature limit. Afterwards, by computing the internal energy density we conclude that the additional terms can be seen as corrections $δσ_{\rm{gup}}$ to the Stefan-Boltzmann law due to GUP effects.
