| contents | 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. |
