The angular momentum of a magnetically trapped atomic condensate
P. Zhang, H. H. Jen, C. P. Sun +1
For an atomic condensate in an axially symmetric magnetic trap, the sum of the axial components of the orbital angular momentum and the hyperfine spin is conserved. Inside an Ioffe…
Time-dependent Fröhlich transformation approach for two-atom entanglement generated by successive passage through a cavity
Yong Li, C. Bruder, C. P. Sun
Time-dependent Fröhlich transformations can be used to derive an effective Hamiltonian for a class of quantum systems with time-dependent perturbations. We use such a transformatio…
Decoherence problem in quantum state transfer via an engineered spin chain
Lan Zhou, Jing Lu, Tao Shi +1
A perfect quantum state transfer(QST) has been shown in an engineered spin chain with "always-on interaction". Here, we consider a more realistic problem for such a protocol, the q…
Quantum criticality in a generalized Dicke model
Yong Li, Z. D. Wang, C. P. Sun
We employ a generalized Dicke model to study theoretically the quantum criticality of an extended two-level atomic ensemble interacting with a single-mode quantized light field. Ef…
Spin entanglement induced by spin-orbit interactions in coupled quantum dots
Nan Zhao, L. Zhong, Jia-Lin Zhu +1
We theoretically explore the possibility of creating spin quantum entanglement in a system of two electrons confined respectively in two vertically coupled quantum dots in the pres…
Analogue of Cavity QED for Coupling between Spin and Nanomechanical Resonator
Fei Xue, Ling Zhong, Yong Li +1
We describe a cavity QED analogue for the coupling system of a spin and a nanomechanical resonator with a magnetic tip. For the quantized nanomechanical resonator, a spin-boson mod…
