DOI: 10.1007/s10909-018-02116-z
Abstract: We have conducted calculations of the coupled dynamics of quantized vortices and fine metallic particles trapped at a free surface of superfluid $$^4\hbox {He}$$4He. The computational result so far indicates that a particle–vortex complex may… read more here.
