量子相空间中$2D$谐振子的Connes距离

Connes distance of $2D$ harmonic oscillators in quantum phase space

Bing-Sheng Lin, Tai-Hua Heng

摘要:

在相空间中研究了$2D$谐振子量子态的Connes距离。利用Hilbert-Schmidt算符形式,构造了玻色子Fock空间和量子Hilbert空间,得到了对应于$4D$量子相空间的Dirac算符和谱三元组.在球条件的基础上,我们得到了关于最优元素的一些约束关系。我们构造了相应的最佳元的显式表达式,并由此导出了$2D$量子谐振子任意两个Fock态之间的Connes距离.我们证明了这些二维距离满足毕达哥拉斯定理。

英文摘要:

We study the Connes distance of quantum states of $2D$ harmonic oscillators in phase space. Using the Hilbert-Schmidt operatorial formulation, we construct a boson Fock space and a quantum Hilbert space, and obtain the Dirac operator and a spectral triple corresponding to a $4D$ quantum phase space. Based on the ball condition, we obtain some constraint relations about the optimal elements. We construct the explicit expressions of the corresponding optimal elements and then derive the Connes distance between two arbitrary Fock states of $2D$ quantum harmonic oscillators. We prove that these two-dimensional distances satisfy the Pythagoras theorem.
