致密QCD彩色磁通量管

Color Magnetic Flux Tubes in Dense QCD

Minoru Eto, Muneto Nitta

摘要:

在重子密度较高时,QCD处于色味锁定相,表现出色超导性。色超导体中最基本的拓扑对象是非阿贝尔涡旋,它是拓扑稳定的色磁通量管。本文给出了彩色磁通量管在不同的耦合常数选择下的数值解。我们还分析研究了它的渐近分布,发现它们不同于通常的超导体的情况。我们提出了色磁通量的宽度,并发现当胶子质量大于标量质量时,色磁通量的宽度大于对胶子康普顿波长的朴素期望。

英文摘要:

QCD is expected to be in the color-flavor locking phase in high baryon density, which exhibits color superconductivity. The most fundamental topological objects in the color superconductor are non-Abelian vortices which are topologically stable color magnetic flux tubes. We present numerical solutions of the color magnetic flux tube for diverse choices of the coupling constants. We also analytically study its asymptotic profiles and find that they are different from the case of usual superconductors. We propose the width of color magnetic fluxes and find that it is larger than naive expectation of the Compton wave length of the massive gluon when the gluon mass is larger than the scalar mass.
