Abstract:

Within a framework of the pseudo-spin formalism we consider the skyrmion-like topological modes for the quasi-two-dimensional quantum lattice bose gas. A skyrmion-skyrmion chiral pseudo-spin coupling results in a pseudo-spin-flip mode splitting to the bonding (ferro) and antibonding (antiferro) quasi-molecular modes with different momentum q-dependence of the effective pseudospin susceptibility. It is conjectured that CuO(2) planes in the doped cuprates can be considered as a system of the skyrmion-like states pinned on the charge inhomogeneity centers. (C) 1999 Elsevier Science B.V.
