Abstract
- Inspired by the method that can deterministically generated the massive entanglement through phase transitions, we study the ground state properties of a spin-1 condensate mixture, under the premise that the heteronuclear spin-exchange collision is taken into account. We developed a effective model to analyze the binary-coupled two-level system and studied the ground state phase transitions. Three representative quantum states with the same number distribution are studied and distinguished through the number fluctuations. We demonstrate that there will be the GreenbergerHorne-Zeilinger (GHZ) state in the mixture if the the extra magnetic field is specifically selected or adiabatically adjusted. One advantage of preparing entangled states in mixtures is that we only need to adjust the external magnetic field, instead of considering the microwaves-magnetic cooperation. Finally we estimate the feasibility of experimentally generating the heteronuclear many-body entanglement in the alkali-metal atomic mixture.<br />Comment: 9 pages, 7 figures
