我们实验研究了当碰撞伙伴生活在不同的维度时发生的混合维散射。我们采用超冷原子的二元混合物，并利用一个物种选择性的一维光学晶格，以限制只有一个原子物种在二维。通过在Feshbach共振附近施加外部磁场，我们调整自由空间散射长度以观察混合维度中的一系列共振。通过监测3体非弹性损耗，我们测量对应的混合维散射共振的磁场值，并找到一个很好的协议与基于简单的能量考虑的理论预测。
We experimentally investigate the mix-dimensional scattering occurring when the collisional partners live in different dimensions. We employ a binary mixture of ultracold atoms and exploit a species-selective 1D optical lattice to confine only one atomic species in 2D. By applying an external magnetic field in proximity of a Feshbach resonance, we adjust the free-space scattering length to observe a series of resonances in mixed dimensions. By monitoring 3-body inelastic losses, we measure the magnetic field values corresponding to the mix-dimensional scattering resonances and find a good agreement with the theoretical predictions based on simple energy considerations.
