GluoN_c等离子体的连续热力学
Continuum Thermodynamics of the GluoN_c Plasma
摘要:
本文研究了N_c=3,4和6的SU(N_c)纯规范理论的热力学性质。通过使用几种不同的晶格间距和体积,获得了诸如压力、能量密度和熵密度等体积量的连续和热力学极限。不存在一个非平凡的保角理论描述体相热力学的温度窗口。我们提取了一级解除禁闭相变的潜热,并观察到良好的标度与N_c。对于我们测量的所有量,强N_c标度都成立,除了可能非常接近转变温度T_c之外;然而,我们无法找到强有力的证据,证明在我们研究的小N_c值下,热量中的t Hooft耦合是标度的。
英文摘要:
We study the thermodynamics of SU(N_c) pure gauge theories for N_c=3, 4 and 6. The continuum and thermodynamic limits of bulk quantities such as the pressure, energy density and the entropy density are taken by using several different lattice spacings and volumes. There is no window of temperature in which a non-trivial conformal theory describes bulk thermodynamics. We extract the latent heat of the first-order deconfinement phase transitions and observe good scaling with N_c. For all quantities that we measure, strong N_c scaling holds, except, possibly, very close to the transition temperature, T_c; however we are unable to find strong evidence for scaling with the 't Hooft coupling in thermal quantities at the small values of N_c which we study.
