摘要：The spin-dependent corrections to the static interquark potential are relevant to describing the
fine and hyper-fine splittings of the heavy quarkonium spectra. We investigate these corrections
in SU(3) lattice gauge theory with the Polyakov loop correlation function as the quark source by
applying the multi-level algorithm. We observe remarkably clean signals for the spin-dependent
potentials up to intermediate distances.
