热力学几何与退禁闭温度

Thermodynamic Geometry and Deconfinement Temperature

Paolo Castorina, Mauro Imbrosciano, Daniele Lanteri

摘要:

将黎曼几何应用于有限温度和重子密度条件下量子色动力学(QCD)的平衡热力学分析,给出了一种计算退禁闭跃迁临界温度$T_c$的新方法.在由强子共振气体的热力学几何描述的受限相中,如果考虑强子排斥体积和相互作用效应,$T_c$的估计结果与夸克-胶子等离子体相的格点量子色动力学模拟结果完全一致.

英文摘要:

The application of Riemannian geometry to the analysis of the equilibrium thermodynamics in Quantum Chromodynamics (QCD) at finite temperature and baryon density gives a new method to evaluate the critical temperature, $T_c$, of the deconfinement transition. In the confined phase, described by the thermodynamic geometry of the Hadron Resonance Gas, the estimate of $T_c$ turns out completely consistent with lattice QCD simulations of the quark-gluon plasma phase if the hadron excluded volume and the interaction effects are taken into account.
