摘要：
The energy of single Skyrmion excitation above the Nagaoka state is being studied numerically in the infinite-U Hubbard model in the limit of small concentration of holes. We find that the energy of a Skyrmion is low compared with energy of other spin excitations being studied, suggesting the Skyrmions may be important in describing the behavior of the infinite-U Hubbard model near half filling.
