查询词典 renormalization group

If we study further the characteristic of this algebraic structure under the action of permutation group elements, it would provide a new approach to solve the problem about the renormalization of noncommutative scalar fields.

如果进一步考察该代数形式在置换群作用下的置换性质，就为我们提供了一种完全解决非对易标量场重整化问题的一种可能途径。

In this paper, the mathematical models, the numerical methods and the kinetic mechanism were systemically studied and improved to meet the requirement. The renormalization group k-εturbulence model was adopted to simulate in-cylinder flows in this article.

本文在三维数学模型中嵌入了化学动力学反应模型，构建了能够深入研究天然气燃烧反应机理、了解天然气发动机燃烧过程的数学模型。

The study of critical phenomena has led to the notions of scaling and universality and has spawned the renormalization group, which shows how identical behavior at long length scales can arise from widely different microscopic interactions.

对临界现象的研究引出了新的尺度分析和普适性的概念，产生了重整化群。重整化群显示了相当不同的微观相互作用是如何在长程尺度范围产生同样的行为。

In this paper, we study the phase diagram of the deformed t-J model in one dimension in the regime where deformation parameter and J/t are both positively small but comparable to each other by using the bosonization field theory and renormalization group technique.

我们利用重整化群方程对相应的相互作用项的标度维数进行了分析并以此来判断相应的电荷与自旋元激发是否存在能隙。同时我们用准经典势的方法讨论了各种序参量在基态能量中的竞争情况。

We presented the extraction of Wilson coefficients, the evolvement of the renormalization group and the definition and current experimental progress of CP violation of B meson.

介绍了Wilson系数的抽取和重整化群演化，B介子系统CP破坏的定义和实验测量现状，给出了相关的理论公式，并对目前和未来的B介子实验做了简要的评述。

This thesis mainly employs the density-matrix renormalization group to investigate the valence bond model. We deal with the one-dimensional and quasi-one dimensional benzenoid systems from medium to infinite sizes successfully and get the ground state energies, the first excited state energies and other properties for the first time.

本论文的主要方面是将密度矩阵重整化群方法引入苯型分子的半经验价键处理，精确计算了一维单层苯型烃及双层苯型烃从小到大，直至无限的基态能量，第一激发态能量及局域芳香性等基本性质。
