讨论了非零重子化学势下的QCD。重点是符号问题的各个方面，这是有关晶格QCD。通过狄拉克算子的谱讨论了自发手性对称性破缺与符号问题的关系。符号问题的强度与夸克质量和化学势有关。讨论了点阵QCD的具体含义。
QCD in the $epsilon$-regime at nonzero baryon chemical potential $mu$ is reviewed. The focus is on aspects of the sign problem which are relevant for lattice QCD. It is discussed how spontaneous chiral symmetry breaking and the sign problem are related through the spectrum of the Dirac operator. The strength of the sign problem is linked to the quark mass and the chemical potential. Specific implications for lattice QCD are discussed.
