标题： Field-induced quantum interference of inelastic scattering in ultracold atomic collisions

摘要： 利用量子干涉在超冷非弹性散射中仍然是一个重大挑战。 在本工作中，我们提出一种方法，以在由各种非弹性散射通道引起的双体损失率中实现可检测的量子干涉。 我们的方法利用“环耦合”配置，通过在超冷原子碰撞过程中结合外部射频和静态电场来实现。 我们对超冷极限下的$^7$Li-$^{41}$K 碰撞进行了闭合耦合计算，以验证我们的提议。 结果表明，双体损失率中显示的干涉图谱在未优化的外部场参数下无法被观察到。 特别是，我们的研究结果表明，在存在射频诱导散射共振的入射通道附近，磁感应的$p$-波共振处，双体损失率系数表现出明显的建设性和破坏性干涉模式。 这些干涉模式随着外部场强度的增加而变得更加显著。 这项工作为控制超冷碰撞中的非弹性散射过程开辟了一条新途径。 显示英文摘要

摘要： xploiting quantum interference remains a significant challenge in ultracold inelastic scattering. In this work, we propose a method to enable detectable quantum interference within the two-body loss rate resulting from various inelastic scattering channels. Our approach utilizes a ``ring-coupling" configuration, achieved by combining external radio-frequency and static electric fields during ultracold atomic collisions. We conduct close-coupling calculations for $^7$Li-$^{41}$K collisions at ultracold limit to validate our proposal. The results show that the interference profile displayed in two-body loss rate is unable to be observed with unoptimized external field parameters. Particularly, our findings demonstrate that the two-body loss rate coefficient exhibits distinct constructive and destructive interference patterns near the magnetically induced $p$-wave resonance in the incoming channel near which a rf-induced scattering resonance exists. These interference patterns become increasingly pronounced with greater intensities of the external fields. This work opens a new avenue for controlling inelastic scattering processes in ultracold collisions.
