低维量子系统中的非弹性约束诱导共振

Inelastic Confinement-Induced Resonances in Low-Dimensional Quantum Systems

Simon Sala, Philipp-Immanuel Schneider, Alejandro Saenz

摘要:

一个理论模型,描述了在最近的损失实验中观察到的限制引起的共振Haller等人。104,153203(2010)]。这些共振起源于由于质心和相对运动的耦合而可能的分子形成。相应的模型进行了验证,从头计算和预测的共振位置在1D以及在2D的限制与实验一致。这解决了实验观测与先前理论预测的矛盾。

英文摘要:

A theoretical model is presented describing the confinement-induced resonances observed in the recent loss experiment of Haller et al. [Phys. Rev. Lett. 104, 153203 (2010)]. These resonances originate from possible molecule formation due to the coupling of center-of-mass and relative motion. A corresponding model is verified by ab initio calculations and predicts the resonance positions in 1D as well as in 2D confinement in agreement with the experiment. This resolves the contradiction of the experimental observations to previous theoretical predictions.
