摘要
Two recent publications report different boundaries for the dimerized phase of the bilinear-biquadratic spin-1 Heisenberg model with quadratic Zeeman effect. We address these discrepancies for the biquadratic model with a quadratic Zeeman term and explain the differences. Based on our numerical results the phase boundaries of the dimerized phase are determined.
