Acoustic-vortex (AV) tweezers ensure stable particle trapping at a zero-pressure center, while particle assembly between two vortex cores is still prevented by the high-potential barrier. Although a one-dimensional low-pressure attractive path of particle assembly can be constructed by the interfere...
