摘要：

By means of the second derivative of the ground-state energy for a finite-size system method, the quantum phase transitions (QPTs) for the frustrated vertically asymmetric diamond chain (VADC) are investigated. Our results display the plentiful frustration induced quantum phases in the model. Meanwhile, using the transfer matrix renormalization group technique (TMRG), we calculate the fidelity susceptibility and magnetic susceptibility of the VADC model in the thermodynamic limit to give a further understanding of the QPTs.
