摘要:

利用普朗克尺度附近各种量子引力理论预言的广义不确定原理(GUP),导出了理想夸克-胶子等离子体(QGP)在强子-QGP相平衡和化学势为零时的热力学性质.有效自由度和MIT袋压力被用来区分强子和部分子阶段。我们发现,GUP作出了不可忽视的贡献,所有的热力学量,特别是在高温下。当考虑GUP方法时,相应的QGP热力学量的渐近行为由Stephan-Boltzmann极限表征。

英文摘要:

The Generalized Uncertainty Principle (GUP), which has been predicted by various theories of quantum gravity near the Planck scale is implemented on deriving the thermodynamics of ideal Quark-Gluon Plasma (QGP) consisting of two massless quark flavors at the hadron-QGP phase equilibrium and at a vanishing chemical potential. The effective degrees of freedom and MIT bag pressure are utilized to distinguish between the hadronic and partonic phases. We find that GUP makes a non-negligible contribution to all thermodynamic quantities, especially at high temperatures. The asymptotic behavior of corresponding QGP thermodynamic quantities characterized by the Stephan-Boltzmann limit would be approached, when the GUP approach is taken into consideration.
