有限密度和温度下的相位猝灭格点量子色动力学

Phase Quenched Lattice QCD at Finite Density and Temperature

D. K. Sinclair, J. B. Kogut

摘要:

我们在相位猝灭近似下模拟了有限夸克数化学势μ下的3味格点量子色动力学,接近于有限温度跃迁。工作接近临界夸克质量,我们没有发现预期的临界终点在小μ的证据。我们正在进行进一步的模拟,旨在计算超流域之外的状态方程,预计其相结构将模仿完整的理论。

英文摘要:

We simulate 3-flavour lattice QCD at finite quark-number chemical potential mu in the phase-quenched approximation, close to the finite temperature transition. Working close to the critical quark mass, we find no evidence for the expected critical endpoint at small mu. We are performing further simulations aimed at calculating the equation-of-state of this theory outside of the superfluid domain, where its phase structure is expected to mimic the full theory.
