Connes spectral distance on twisted fuzzy torus
Zhi-Kang You, Bing-Sheng Lin
In this paper, we study the Connes spectral distance between states on the fuzzy torus. We construct a Dirac operator by commutators and anticommutators. Based on this Dirac operat…

Unitary invariance of Connes spectral distances of quantum states
Ji-Hong Wang, Bing-Sheng Lin, Zhi-Kang You
In this paper, we study the properties of Connes spectral distances between quantum states under unitary transformations. We mainly focus on spectral triples with matrix algebras a…
