有限温度下规范拓扑的关联和涨落

Correlations and fluctuations of the gauge topology at finite temperatures

Rasmus Larsen, Edward Shuryak

摘要:

瞬变双子是拓扑孤子--杨-米尔斯方程的解--在非零温度下出现在非平凡期望值$A_0$处。使用我们以前的工作中产生的那些,为2色和2味QCD,下面和上面的去精细手征相变的合奏,我们研究它们之间的相关性,以及在总体积的子体积中的几个全局电荷的波动。所确定的关联长度是强子质量的有限- $T$延拓,如$η'$介子的有限-$T$延拓.

英文摘要:

Instanton-dyons are topological solitons -- solutions of Yang-Mills equations -- which appear at non-trivial expectation value of $A_0$ at nonzero temperatures. Using the ensembles of those, generated in our previous work, for 2-color and 2-flavor QCD, below and above the deconfinement-chiral phase transition, we study the correlations between them, as well as fluctuations of several global charges in the sub-volumes of the total volume. The determined correlation lengths are the finite-$T$ extension of hadronic masses, such as that of $η'$ meson.
