摘要:

一种计算康纳斯谱距离的算法,适用于非对易量子力学的希尔伯特-施密特算符公式,通过引入适当的谱三元组,并用于计算Moyal平面上的无穷小距离,揭示了几何和统计之间的深刻联系。本文利用同样的算法,对空间坐标满足$su(2)$代数的模糊球,用Hilbert-Schmidt算子公式计算了Connes谱距离。这已经计算的离散,以及Perelemov的$SU(2)$相干态。在这里,我们也得到了几何和统计之间的联系,这是通过计算一个特定的模糊球的量子希尔伯特空间上的混合态之间的无穷小距离,索引为$n\in\mathbb{Z}/2$。

英文摘要:

An algorithm to compute Connes spectral distance, adaptable to the Hilbert-Schmidt operatorial formulation of non-commutative quantum mechanics, was developed earlier by introducing the appropriate spectral triple and used to compute infinitesimal distances in the Moyal plane, revealing a deep connection between geometry and statistics. In this paper, using the same algorithm, the Connes spectral distance has been calculated in the Hilbert-Schmidt operatorial formulation for the fuzzy sphere whose spatial coordinates satisfy the $su(2)$ algebra. This has been computed for both the discrete, as well as for the Perelemov's $SU(2)$ coherent state. Here also, we get a connection between geometry and statistics which is shown by computing the infinitesimal distance between mixed states on the quantum Hilbert space of a particular fuzzy sphere, indexed by $n\in\mathbb{Z}/2$.
