我们将状态密度方法推广到规范系统（LLR方法），在有限温度和密度下，用重夸克来研究QCD。该方法具有指数误差抑制，并在超过一百个数量级的范围内产生Polyakov环概率分布函数。SU（2）规范理论被认为是在禁闭和高温阶段，并在有限密度的重夸克。在后一种情况下，观察到密度随化学势的平稳上升，并且没有发现与由于有限密度而导致的去禁闭相关联的临界现象。
We extend the density-of-states approach to gauge systems (LLR method) to QCD at finite temperature and density with heavy quarks. The approach features an exponential error suppression and yields the Polyakov loop probability distribution function over a range of more than hundred orders of magnitude. SU(2) gauge theory is considered in the confinement and the high-temperature phase, and at finite densities of heavy quarks. In the latter case, a smooth rise of the density with the chemical potential is observed, and no critical phenomenon associated with deconfinement due to finite densities is found.
