2+1维Yang-Mills基态与时间规范
Yang-Mills Ground State in 2+1 Dimensions and Temporal Gauge
摘要:
本文提出了一个规范不变的波泛函作为2+1维Yang-Mills理论的基态的近似,在时间规范中量子化。所提出的真空态在自由场极限和零模强场极限下都是相应哈密顿量的真实基态。禁闭,在这种方法中,产生通过降维,我们提出的质量间隙的数值结果。对彩色加网的问题进行了简要的讨论。
英文摘要:
A gauge-invariant wavefunctional is proposed as an approximation to the ground state of Yang-Mills theory in 2+1 dimensions, quantized in temporal gauge. The proposed vacuum state is the true ground state of the appropriate Hamiltonian in both the free-field limit, and in a zero mode strong-field limit. Confinement, in this approach, arises via dimensional reduction, and we present numerical results for the mass gap. The issue of color screening is briefly discussed.
