我们首次在实验上实现了在有引力的情况下，由射频磁场包裹的纯磁囚禁中的二维量子气体。由此产生的电势是非常平滑的，并且非常接近二维禁闭平面中的谐和。我们完全刻画了陷阱的特征，并演示了量子气体在两个维度上的限制。陷阱的几何形状可以在很大程度上被修改，特别是以动态的方式。利用这一可能性，我们研究了二维玻色气体的单极和四极模。
We present the first experimental realization of a two-dimensional quantum gas in a purely magnetic trap dressed by a radio frequency field in the presence of gravity. The resulting potential is extremely smooth and very close to harmonic in the two-dimensional plane of confinement. We fully characterize the trap and demonstrate the confinement of a quantum gas to two dimensions. The trap geometry can be modified to a large extent, in particular in a dynamical way. Taking advantage of this possibility, we study the monopole and the quadrupole modes of a two-dimensional Bose gas.
