论文摘要
我们研究了弗里德伯格 - 李模型中通过均匀的气泡成核驱动的强一阶夸克 - 哈德隆转变的动力学。该模型的一环有效热力学潜力和临界气泡曲线已经在不同的温度和化学电位上计算出来。通过将温度和化学势作为变量,表面张力的演变,临界气泡的典型半径以及在存在成核气泡的情况下粗晶的自由能的变化,并且还相应地解决了薄壁近似值的可靠性的极限。将我们的结果与弱一阶夸克 - 戴隆相变的结果进行比较,尤其是旋缺骨分解是相关的。
We investigate the dynamics of a strong first-order quark-hadron transition driven by cubic interaction via homogeneous bubble nucleation in the Friedberg-Lee model. The one-loop effective thermodynamics potential of the model and the critical bubble profiles have been calculated at different temperatures and chemical potentials. By taking the temperature and the chemical potential as the variables, the evolutions of the surface tension, the typical radius of the critical bubble and the shift in the coarse-grained free energy in the presence of a nucleation bubble are obtained and the limit on the reliability of the thin-wall approximation is also addressed accordingly. Our results are compared to those obtained for a weak first-order quark-hadron phase transition, especially the spinodal decomposition is relevant.
