Quantum Phase Transitions of the Distorted Diamond Spin Chain
Tomosuke Zenda, Yuta Tachibana, Yuki Ueno +2
The frustrated quantum spin system on the distorted diamond chain lattice suitable for the alumoklyuchevskite is investigated using the numerical diagonalization of finite-size clu…
Quantum Phase Transition of the Twisted Spin Tube
Yuta Tachibana, Yuki Ueno, Tomosuke Zenda +2
The twisted three-leg spin tube with the lattice distortion from the regular triangle to the isosceles one is investigated using the numerical diagonalization of finite-siz…
Magnetization Plateau of the Distorted Diamond Spin Chain
Yuki Ueno, Tomosuke Zenda, Yuta Tachibana +2
The frustrated quantum spin system on the distorted diamond chain lattice is investigated using the numerical diagonalization of finite-size clusters and the level spectroscopy ana…
Spin Nematic Liquids of the Spin Ladder in Magnetic Field
Tôru Sakai, Kiyomi Okamoto
The magnetization process of the spin ladder system is investigated using the numerical exact diagonalization of finite-size clusters. The field-induced spin nematic liquid p…
Ground-State Phase Diagram of an Anisotropic S=1 Ferromagnetic-Antiferromagnetic Bond-Alternating Chain
Kiyomi Okamoto, Takashi Tonegawa, Makoto Kaburagi +1
By using mainly numerical methods, we investigate the ground-state phase diagram (GSPD) of an ferromagnetic-antiferromagnetic bond-alternating chain with the and the on…
Haldane Gaps of Large-S Heisenberg Antiferromagnetic Chains and Asymptotic Behavior
Hiroki Nakano, Norikazu Todoroki, Toru Sakai
The one-dimensional Heisenberg antiferromagnets of large-integer- spins are studied; their Haldane gaps are estimated by the numerical diagonalization method for and .…
