使用有限尺寸簇的数值对角化研究 S= 1/2 kagome 晶格反铁磁体。零磁化强度下的磁化率分析表明系统的磁激励是无间隙的。这与我们之前对自旋间隙的有限尺度分析是一致的。该方法在三角晶格反铁磁体中的应用证实了分析的有效性。
The S= 1/2 kagome-lattice antiferromagnet is investigated using the numerical diagonalization of finite-size clusters. The analysis of the susceptibility at the zero magnetization indicates that the magnetic excitation of the system is gapless. It is consistent with our previous finite-scaling analysis of the spin gap. The application of the method for the triangular-lattice antiferromagnet confirms the validity of the analysis.
