标题： QCD at non-zero temperature and density from the lattice

摘要： 研究中子星核心和重离子碰撞实验等截然不同的系统需要理解有限温度 \(T\) 和化学势 \(\mu_q\) 下的 QCD 相结构。 我们回顾了在非零 \(\mu_q\) 条件下进行格点 QCD 模拟的一些困难，并概述了用于克服这一问题的重加权方法。 此方法用于确定 QCD 在 (\(\mu_q\), \(T\)) 平面上的临界端点。 我们在小 \(\mu_q\) 下研究压力和夸克数磁化率。 显示英文摘要

摘要： The study of systems as diverse as the cores of neutron stars and heavy-ion collision experiments requires the understanding of the phase structure of QCD at non-zero temperature, T, and chemical potential, mu_q. We review some of the difficulties of performing lattice simulations of QCD with non-zero mu_q, and outline the re-weighting method used to overcome this problem. This method is used to determine the critical endpoint of QCD in the (mu_q,T) plane. We study the pressure and quark number susceptibility at small mu_q.
