Deformation quantization for systems with second-class constraints in deformed fermionic phase space
Bing-Sheng Lin, Tai-Hua Heng
In order to quantize systems involving second-class constraints, one should use Dirac bracket instead of Poisson bracket. Furthermore, one can specify a star product in which the t…
Connes spectral distances, quantum discord and coherence of qubits
Bing-Sheng Lin, Zi-Hao Xu, Ji-Hong Wang +1
We construct spectral triples of one- and two-qubit states using the Hilbert-Schmidt operatorial formulation, and study the Connes spectral distances. We also construct the Dirac o…
Connes spectral distance and nonlocality of generalized noncommutative phase spaces
Bing-Sheng Lin, Tai-Hua Heng
We study the Connes spectral distance of quantum states and analyse the nonlocality of a 4D generalized noncommutative phase space. By virtue of the Hilbert-Schmidt operatorial for…
Curvature, area and Gauss-Bonnet formula of the Moyal sphere
Han-Liang Chen, Bing-Sheng Lin
We studied some geometric properties of the Moyal sphere. Using the conformal metric of the sphere in ordinary space and the matrix basis, we calculated the scalar curvature, total…
