摘要
详细计算了环形阱中单分量BEC平面波解的波戈留波夫激发,得到了精确的激发谱.分析了平面波稳定的参数区域,发现可通过调节原子间的相互作用强度来控制平面波的动力学稳定性与不稳定性,并对理论推导结果进行了数值模拟验证.
After detailed calculation of the bogoliubov analysis of plane wave solutions of Bose-Einstein condensate in a rotating ring trap,we gotthe exactexcitation spectrum.Thenwe Analyzed the parameterregionof stability and found that the stability and instability of plane waves could be controlled by modulating the interaction strength.Finally the theoretical resultwas demonstrated by simulation calculation.
