我们提出了在自旋为1的玻色-爱因斯坦凝聚体中,通过自旋交换相互作用的时间调制来局域化自旋混合动力学,这种时间调制可以用光学Feshbach共振来调谐。采用相干控制技术,我们证明了{sup 87}Rb原子凝聚体中自旋混合动力学的局域化和冻结,以及内禀动力学不稳定性和自发自旋畴形成的抑制。这项工作指出了一个有前途的计划,调查弱磁自旋偶极相互作用,这通常是掩盖了更占主导地位的自旋交换相互作用。
We propose to localize spin mixing dynamics in a spin-1 Bose-Einstein condensate by a temporal modulation of spin exchange interaction, which is tunable with optical Feshbach resonance. Adopting techniques from coherent control, we demonstrate the localization and freezing of spin mixing dynamics, and the suppression of the intrinsic dynamic instability and spontaneous spin domain formation in a ferromagnetically interacting condensate of {sup 87}Rb atoms. This work points to a promising scheme for investigating the weak magnetic spin dipole interaction, which is usually masked by the more dominant spin exchange interaction.
