| 英文摘要 | By means of the second derivative of the ground-state and first-excited energy, the quantum phase transitions (qpts) for the distorted diamond chain (ddc) with ferromagnetic and antiferromagnetic frustrated interactions and the trimerized case are investigated, respectively. our results show the plentiful quantum phases owing to the spin interaction competitions in the model. meanwhile, by using the transfer-matrix renormalization-group technique, we study the two-site thermal entanglement of the ddc model in the thermodynamic limit for a further understanding of the qpts. |
