Spin excitation of the Heisenberg antiferromagnet with frustration: from the bounce-lattice antiferromagnet through the maple-leaf-lattice antiferromagnet to the exact-dimer system
Hiroki Nakano, Toru Sakai
The spin-S Heisenberg antiferromagnet on the two-dimensional lattice is investigated for S=1/2 and S=1. We consider interaction at isolated dimers () and interaction bon…
Numerical Diagonalization Study of the Phase Boundaries of the S=2 Heisenberg Antiferromagnet on the Orthogonal Dimer Lattice
Hiroki Nakano, Toru Sakai, Yuko Hosokoshi
The S=2 Heisenberg antiferromagnet on the orthogonal dimer lattice is studied. The edges of the exact dimer and Neel-ordered phases in the ground state of the system are examined b…

Collapsing Behavior of the Ferrimagnetic Ground State of the Heisenberg Antiferromagnet on the Lieb Lattice due to Frustration
Rito Furuchi, Hiroki Nakano, Tôru Sakai
We study the Heisenberg antiferromagnet on the Lieb lattice accompanied by additional interactions that create frustration. The system exhibits a ferrimagnetic ground sta…
Translational symmetry broken magnetization plateau of the S=1 antiferromagnetic Heisenberg chain with competing anisotropies
Tôru Sakai, Kiyomi Okamoto, Kouichi Okunishi +4
We investigate the S=1 antiferromagnetic quantum spin chain with the exchange and single-ion anisotropies in a magnetic field, using the numerical exact diagonalization of finite-s…
