| 英文摘要 | We consider a novel system of two-component atomic Bose-Einstein condensate in a double-well potential. Based on the well-known two-mode approximation, we demonstrate that there are obvious avoided level-crossings when both interspecies and intraspecies interactions of two species are increased. The quantum dynamics of the system exhibits revised oscillating behaviours compared with a single component condensate. We also examine the entanglement of two species. Our numerical calculations show that the onset of entanglement can be signalled by a violation of the Cauchy-Schwarz inequality of a second-order cross-correlation function. Consequently, we use Von Neumann entropy to quantify the degree of entanglement. |
