| 内容記述 | Frustrated quantum spin systems are investigated by the large-scale numerical exact diagonalization based on the Lanczos algorithm. Our recent results based on the calculation for finite-size clusters up to 45 spins are introduced about the following topics; (1) spin gap issue of the kagome-lattice antiferromagnet[1.2], (2) magnetization plateaux of the triangular- and kagome-lattice antiferromagnets[3,4]. (3) quatnum phase transitions of the Shastry-Sutherland model[5]. References [1]H. Nakano and T. Sakai, J. Phys. Soc. Jpn. 80 (2011)053704;arXiv:1103.5829 [2]T. Sakai and H.
