论文摘要
我们报告了观察到晶格潜力中强三维（3D）限制的约束引起的共振。从主要单位占用率的Mott-unsulator状态开始，我们在特定值下检测到损失和加热特征的限制长度和3D散射长度。两个独立的模型基于质量中心中心与粒子的相对运动之间的耦合，这些模型被晶格介导，预测共振位置将达到良好的近似值，这表明是普遍的行为。我们的结果将限制引起的共振扩展到任何维度，并在强3D限制下打开了一种相互作用调整和受控分子形成的替代方法。
We report on the observation of confinement-induced resonances for strong three-dimensional (3D) confinement in a lattice potential. Starting from a Mott-insulator state with predominantly single-site occupancy, we detect loss and heating features at specific values for the confinement length and the 3D scattering length. Two independent models, based on the coupling between the center-of-mass and the relative motion of the particles as mediated by the lattice, predict the resonance positions to a good approximation, suggesting a universal behavior. Our results extend confinement-induced resonances to any dimensionality and open up an alternative method for interaction tuning and controlled molecule formation under strong 3D confinement.
