1)next-nearest-neighbor hopping次近邻电子跳跃 1.On the basis of BBV model, we considered the effects ofnext-nearest-neighbor hoppingon the energy structure, the lattice configuration and the charge density of the positive and negative solitons in pernigranine-base polymer.本文从BBV模型出发并加以修...
We study localization in polymer chains modeled by the nonlinear discrete Schrodinger equation (DNLS) with next-nearest-neighbor (n-n-n) interaction extending beyond the usual nearest-neighbor exchange approximation. Modulational instability of plane carrier waves is discussed and it is shown that ...

A next-nearest-neighbor hopping t' in the t-t'-J model has a different sign between the hole- and electron-doped systems of high-Tc cuprates: t'0 for the electron-doped system. We show that the sign is responsible for the remarkable difference of antiferromagnetic (AF) phases between th...
We investigate a fully frustrated XY model with nearest-neighbor (NN) and next-nearest-neighbor (NNN) couplings which can be realized in Josephson junction arrays. We study the phase diagram for 0<=x<=1 (x is the ratio between NNN and NN couplings). When x<1/2 an Ising transition and...

We study magnetization transport at high temperatures in several spin ladder systems as well as in next-nearest-neighbor coupled spin chains. In the integrable ladder considered we analytically show that the transport is ballistic in sectors with nonzero average magnetization, while numerical simulations...
The existence of a disorder point Tis established for some one- and two-dimensional Ising lattices with antiferromagnetic next-nearest-neighbor interactions. Within the disordered phase, the decay of axial next-nearest-neighbor pair correlations with increasing spin separation is positive monotonic exponen...
Based on the lattice hydrodynamic model with bidirectional pedestrian flow, the lattice hydrodynamic model which considered the interaction of the next-nearest-neighbor pedestrians was proposed in this paper. By the linear stability analysis, the stability condition was obtained. By nonlinear analysis, th...
