QCD的一个有效模型

An Effective Model of QCD Monopoles

Adith Ramamurti, Edward Shuryak

摘要:

本文通过对单组分和双组分库仑玻色系统的路径积分的数值模拟,对磁系综进行了量子多体研究。用超流分数的有限尺寸标度和置换循环的统计分析两种方法得到了玻色-爱因斯坦凝聚相变的临界温度与库仑耦合强度之间的关系。在找到与我们系统中测得的相关函数相匹配的参数后,我们得到了一个有效的QCD色磁单极子量子模型。从这个匹配的模型中,我们能够提取出$T_\text{c}$附近的量子色动力学状态方程的贡献。

英文摘要:

In this work, we carried out quantum many-body studies of magnetic monopole ensembles through numerical simulations of the path integral for one- and two-component Coulomb Bose systems. We found the relation between the critical temperature for the Bose-Einstein condensation phase transition and the Coulomb coupling strength using two methods, the finite-size scaling of the superfluid fraction and statistical analysis of permutation cycles. After finding parameters that match the correlation functions measured in our system with the correlation functions previously measured on the lattice, we arrived at an effective quantum model of color magnetic monopoles in QCD. From this matched model, we were able to extract the monopole contribution to QCD equation of state near $T_\text{c}$.
