摘要: The bulk properties and impurity effect in the one-dimensional S =1/2 Heisenberg model with dimerization next-nearest-neighbor exchange are studied by density matrix renormalization group exact diagonalization methods. This widely covers =1 model, two-leg ladders, bond-alternating chains model. Almost whole parameter space belongs to Haldane phase. In non-dimerizing limit a transition kind of spin liquid takes place, characterized delocalized polarization. causes distinct effects between spin-Peierls compound CuGeO 3 systems. Experimental aspects CuNb 2 O 6 also discussed. Furthermore, incommensurate correlation arising this is extensively studied, phase diagram constructed.
