Dynamical symmetry of Dirac hydrogen atom with spin symmetry and its connection with Ginocchio's oscillator
Fu-Lin Zhang, Bo Fu, Jing-Ling Chen
The Dirac hydrogen atom with spin symmetry is shown has a SO(4) symmetry. The generators are derived, and the corresponding Casimir operator leads to the energy spectrum naturally.…
All Pure Two-Qudit Entangled States Can be Generated via a Universal Yang--Baxter Matrix Assisted by Local Unitary Transformations
Jing-Ling Chen, Kang Xue, Mo-Lin Ge
We show that all pure entangled states of two -dimensional quantum systems (i.e., two qudits) can be generated from an initial separable state via a universal Yang--Baxter matri…
Berry phase and quantum criticality in Yang--Baxter systems
Jing-Ling Chen, Kang Xue, Mo-Lin Ge
Spin interaction Hamiltonians are obtained from the unitary Yang--Baxter -matrix. Based on which, we study Berry phase and quantum criticality in the Yang--Baxter system…
Braiding transformation, entanglement swapping and Berry phase in entanglement space
Jing-Ling Chen, Kang Xue, Mo-Lin Ge
We show that braiding transformation is a natural approach to describe quantum entanglement, by using the unitary braiding operators to realize entanglement swapping and generate t…
Quantum dynamical theory for squeezing the output of a Bose-Einstein condensate
Hui Jing, Jing-Ling Chen, Mo-Lin Ge
A linear quantum dynamical theory for squeezing the output of the trapped Bose-Einstein condensate is presented with the Bogoliubov approximation. We observe that the non-classical…
A Unified Treatment for XXX-Heisenberg Model and Haldane-Shastry Model Using Shift Operators
Jing-Ling Chen, Mo-Lin Ge, Kang Xue +1
A unified treatment is developed for the XXX-Heisenberg model and a long-ranged interaction model (the in Haldane-Shastry model) from the point of view of shift operators (or…
