| 英文摘要 | An impurity bond J' in a periodic one-dimensional antiferromagnetic spin-1 chain with exchange J is considered. Using the numerical density matrix renormalization-group method, we find an impurity energy level in the Haldane gap, corresponding to a bound state near the impurity bond. When J'J. The impurity level appears only when the deviation dev=(J'-J)/J' is greater than B-c, which is close to 0.3 in our calculation. |
