Abstract: We study the (de)localization phenomena of one-component lattice fermions in spin backgrounds. The O(3) classical spin variables on sites fluctuate thermally through the ordinary nearest-neighbor coupling. Their complex two-component ($\mathrm{CP}{}^{1}$-Schwinger boson) representation forms a composite… read more here.
