Quantum magnetism of the spin-1 kagome-lattice antiferromagnet
Katsuhiro Morita
We investigate the spin-1 kagome-lattice Heisenberg antiferromagnet using large-scale Lanczos diagonalization and the finite-temperature Lanczos method. The zero-temperature magnet…

Valence Bond Crystal Ground State of the 1/9 Magnetization Plateau in the Spin-1/2 Kagome Lattice
Katsuhiro Morita
We investigate the ground state of a spin-1/2 kagome antiferromagnet at the 1/9 magnetization plateau, focusing primarily on six types of valence bond crystal (VBC) distortions. Am…

Kazu Bodaiji, Katsuhiro Morita, Yoshiyuki Fukumoto
A recently discovered kagome antiferromagnet has attracted significant interest due to its unique kagome lattice structure and magnetic p…
