Quantum Entanglement of Excitons in Coupled Quantum Dots
Ping Zhang, C. K. Chan, Qi-Kun Xue +1
Optically-controlled exciton dynamics in coupled quantum dots is studied. We show that the maximally entangled Bell states and Greenberger-Horne-Zeilinger (GHZ) states can be robus…
Dynamics of a two-component atomic Bose-Einstein condensate
Ping Zhang, C. K. Chan, Xiang-Gui Li +1
The dynamical population oscillations between two internal states of a Bose-Einstein condensate are investigated within the rotating wave approximation. Analytical expressions for…
Dynamics of spin-2 Bose condensate driven by external magnetic fields
Ping Zhang, C. K. Chan, Xiang-Gui Li +2
Dynamic response of the F=2 spinor Bose-Einstein condensate (BEC) under the influence of external magnetic fields is studied. A general formula is given for the oscillation period…
Coulomb-enhanced dynamic localization and Bell state generation in coupled quantum dots
Ping Zhang, Qi-Kun Xue, Xian-Geng Zhao +1
We investigate the dynamics of two interacting electrons in coupled quantum dots driven by an AC field. We find that the two electrons can be trapped in one of the dots by the AC f…
Spin-Dependent Transport Through An Interacting Quantum Dot
Ping Zhang, Qi-Kun Xue, Yu-Peng Wang +1
We study the nonequilibrium spin transport through a quantum dot containing two spin levels coupled to the magnetic electrodes. A formula for the spin-dependent current is obtained…
