    Quantum HeisenbergS=1/2 spin glass with ferromagnetic coupling and random Dzyaloshinskii-Moriya interactions

    By means of the generalized static replica symmetric spin glass theory, a quantum HeisenbergS=1/2 spin glass model with the infinite-ranged random Dzyaloshinskii-Moriya (DM) interaction and ferromagnetic coupling...

    Effects of the second and third neighbor hop** interactions on the electronic states of soliton in polyacetylene

    We have studied the energy spectra and the electronic states of a soliton in the weakly coupled electron-phonon systems using an extension of SSH model that includes non-nearest neighbor hop** interactions. ...

    Effects of the coulomb interaction on the 2D localized modes of soliton in the photoexcited polyacetylene

    We have studied the effects of electron-electron interaction on the 2D localized modes of a soliton using the two-dimensional model that includes the bond-bending term and pinning effects in the photoexcited s...
