论文摘要
尽管在旋转轨道耦合的玻色 - 因斯坦冷凝物中对超偏度的开创性观察到，但直到现在，新出现的空间周期性密度调制的动力学却得到了极大的探索。在这里，我们证明了这种超滤光度凝结物中密度条纹的非差异，并探索了其动态行为，但会受到旋转扰动的影响。我们在无限系统中进行了分析表明，在存在谐波陷阱的情况下，我们以晶体波的形式影响超olid的密度曲线，从而诱导周期性的振荡以及边缘的方向。这两个功能都很好地触及了当今的实验。我们的结果表明，该系统是一种范式的超级固体，具有与完全动态的晶体结构结合的超流量。
Despite ground-breaking observations of supersolidity in spin-orbit-coupled Bose-Einstein condensates, until now the dynamics of the emerging spatially periodic density modulations has been vastly unexplored. Here, we demonstrate the nonrigidity of the density stripes in such a supersolid condensate and explore their dynamic behavior subject to spin perturbations. We show both analytically in infinite systems and numerically in the presence of a harmonic trap how spin waves affect the supersolid's density profile in the form of crystal waves, inducing oscillations of the periodicity as well as the orientation of the fringes. Both these features are well within reach of present-day experiments. Our results show that this system is a paradigmatic supersolid, featuring superfluidity in conjunction with a fully dynamic crystalline structure.
