SU(n)系统的广义相干态

Generalized coherent states for SU(n) systems

Kae Nemoto

摘要:

对任意$n$的SU(n)系统,发展了广义相干态.这是通过首先迭代地确定SU(n)相干态的显式表示,然后确定对应用有用的参数表示来完成的。对于SU(n),相干态的集合同构于陪集空间$SU(n)/SU(n-1)$,从而显示陪集空间的几何结构。这些结果为描述任意SU(n)系统提供了一个方便的$(2n - 1)$ -维空间.进一步得到了陪集空间上的度规和测度,并给出了SU(n)相干态的一些性质。

英文摘要:

Generalized coherent states are developed for SU(n) systems for arbitrary $n$. This is done by first iteratively determining explicit representations for the SU(n) coherent states, and then determining parametric representations useful for applications. For SU(n), the set of coherent states is isomorphic to a coset space $SU(n)/SU(n-1)$, and thus shows the geometrical structure of the coset space. These results provide a convenient $(2n - 1)$--dimensional space for the description of arbitrary SU(n) systems. We further obtain the metric and measure on the coset space, and show some properties of the SU(n) coherent states.
