Prepotential approach to systems with dynamical symmetries
Yan Li, Fu-Lin Zhang, Jing-Ling Chen +1
A prepotential approach to constructing the quantum systems with dynamical symmetry is proposed. As applications, we derive generalizations of the hydrogen atom and harmonic oscill…
Higgs algebraic symmetry of screened system in a spherical geometry
Yan Li, Fu-Lin Zhang, Jing-Ling Chen
The orbits and the dynamical symmetries for the screened Coulomb potentials and isotropic harmonic oscillators have been studied by Wu and Zeng [Z. B. Wu and J. Y. Zeng, Phys. Rev.…
Requirement of Dissonance in Assisted Optimal State Discrimination
Fu-Lin Zhang, Jing-Ling Chen, L. C. Kwek +1
A fundamental problem in quantum information is to explore what kind of quantum correlations is responsible for successful completion of a quantum information procedure. Here we st…
Berry phases for interacting spins in composite environments
Da-Bao Yang, Fu-Lin Zhang, Jing-Ling Chen
Due to the potential application in quantum information process, geometric phase of interacting system arouse many interests. Some physicists concentrate on the system in pure clas…
Most robust and fragile two-qubit entangled states under depolarizing channels
Chao-Qian Pang, Fu-Lin Zhang, Yue Jiang +2
For a two-qubit system under local depolarizing channels, the most robust and most fragile states are derived for a given concurrence or negativity. For the one-sided channel, the…
