One-dimensional spin pyrochlore lattice: exact ground state and elementary excitations
Shu Chen, Yupeng Wang, W. Q. Ning +2
We study the antiferromagnetic spin exchange models with and S=1 on a one-dimensional tetrahedron chain by both analytical and numerical approaches. The system is shown to…

Phonon Effects on Spin-Charge Separation in One Dimension
W. Q. Ning, Hui Zhao, C. Q. Wu +1
Phonon effects on spin-charge separation in one dimension are investigated through the calculation of one-electron spectral functions in terms of the recently developed cluster per…
