论文摘要
具有足够沉重的动力夸克的QCD的热力学可以通过三维Polyakov环的有效理论来描述，该理论在截短的特征和跳跃膨胀后获得。我们通过平均场方法研究了低温的结果相图。考虑到Baryon数字和同胞的化学潜力，我们以$μ_i= 0 $的液体气体类型过渡到Baryon物质的明显信号，而Bose-Einstein Condensation Transition在$μ_b= 0 $中以及两种化学势时的连接时都以$μ__b= 0 $的形式获得。
The thermodynamics of QCD with sufficiently heavy dynamical quarks can be described by a three-dimensional Polyakov loop effective theory, obtained after a truncated character and hopping expansion. We investigate the resulting phase diagram for low temperatures by mean field methods. Taking into account chemical potentials for both baryon number and isospin, we obtain clear signals for a liquid-gas type transition to baryon matter at $μ_I=0$ and a Bose-Einstein condensation transition at $μ_B=0$, as well as for their connection when both chemical potentials are non-zero.
