二维SU(N)Yang-Mills理论的混合蒙特卡罗方法初步研究

Preliminary study of two-dimensional SU(N) Yang-Mills theory with adjoint matter by Hybrid Monte Carlo approach

Piotr Korcyl, Mateusz Koren

摘要:

二维非阿贝尔量子场模型为具有规范对称性的量子理论的解析和数值研究提供了一个有用的实验室。它们可以表现出各种各样的特征,例如电荷限制,这是从D=4理论如QCD中已知的。几个解析预测的二维系统的光谱与伴随物质的假设和数值结果得到了使用离散光锥量子化技术,但他们都没有通过蒙特卡罗模拟检查。在这封信中,我们提出了两个这样的模型,这是特别有趣的从物理的角度来看,并讨论第一个数值结果。

英文摘要:

Two-dimensional non-abelian quantum field models provide a useful laboratory for analytic and numerical investigations of quantum theories with gauge symmetry. They can exhibit various features, such as charge confinement, which are known from D=4 theories like QCD. Several analytic predictions concerning the spectra of two-dimensional systems with adjoint matter were postulated and numerical results were obtained using Discrete Light Cone Quantization techniques, however none of them has been checked via Monte Carlo simulations. In this Letter we present two such models which are particularly interesting from the physical point of view and discuss first numerical results.
