Uncertainty relations based on Wigner-Yanase skew information
Xiaofen Huang, Tinggui Zhang, Naihuan Jing
In this paper, we use certain norm inequalities to obtain new uncertain relations based on the Wigner-Yanase skew information. First for an arbitrary finite number of observables w…
Trade-off relations of l_1-norm coherence for multipartite systems
Zhengmin Jiang, Tinggui Zhang, Xiaofen Huang +1
We study the trade-off relations given by the l_1-norm coherence of general multipartite states. Explicit trade-off inequalities are derived with lower bounds given by the coherenc…
Separability criteria based on Heisenberg-Weyl representation of density matrices
Jingmei Chang, Meiyu Cui, Tinggui Zhang +1
Separability is an important problem in theory of quantum entanglement. By using the Bloch representation of quantum states in terms of the Heisenberg-Weyl observable basis, we pre…
Dynamics and Spreading Speed of a Reaction-Diffusion System with Advection Modeling West Nile Virus
Chengcheng Cheng, Zuohuan Zheng
This paper aims to explore the temporal-spatial spreading and asymptotic behaviors of West Nile virus by a reaction-advection-diffusion system with free boundaries, especially cons…
