模糊几何的物质引力耦合与Landau-Hall问题

Matter-gravity coupling for fuzzy geometry and the Landau-Hall problem

V. P. Nair

摘要:

我们考虑一组物理自由度耦合到一个有限维的希尔伯特空间,它可以被视为建模的模糊空间或作为最低的朗道水平的朗道霍尔问题。这些可以被看作是模糊空间上的物质场。顺序推广到任意背景,我们认为,有效的作用量是由陈-西蒙斯形式与狄拉克指数密度(与规范和引力场),与阿贝尔规范场移动的庞加莱-Cartan形式的物质动力学。其结果是一个行动的物质领域的拉格朗日积分密度是一个特定的多项式的曲率。

英文摘要:

We consider a set of physical degrees of freedom coupled to a finite-dimensional Hilbert space, which may be taken as modeling a fuzzy space or as the lowest Landau level of a Landau-Hall problem. These may be viewed as matter fields on a fuzzy space. Sequentially generalizing to arbitrary backgrounds, we argue that the effective action is given by the Chern-Simons form associated with the Dirac index density (with gauge and gravitational fields), with an abelian gauge field shifted by the Poincaré-Cartan form for matter dynamics. The result is an action for matter fields where the Lagrangian is integrated with a density which is a specific polynomial in the curvatures.
