论文摘要
我们研究QCD中的解元过渡线,用于夸克化学势最高$μ_Q\ sim 5 t $($μ_b\ sim 15 t $)。为了避免符号问题,我们将复杂的langevin方程与量规冷却。 Plaquette仪表作用与两种幼稚的威尔逊费米斯的口味相对较重,大约为1.3 GEV。二次依赖性在整个化学势范围内很好地描述了过渡线。
We study the deconfinement transition line in QCD for quark chemical potentials up to $μ_q \sim 5 T$ ($μ_B \sim 15 T$). To circumvent the sign problem we use the complex Langevin equation with gauge cooling. The plaquette gauge action is used with two flavors of naive Wilson fermions at a relatively heavy pion mass of roughly 1.3 GeV. A quadratic dependence describes the transition line well on the whole chemical potential range.
