Spin-chirality duality in a spin ladder with four-spin cyclic exchange
Toshiya Hikihara, Tsutomu Momoi, Xiao Hu
Effect of four-spin cyclic exchange on magnetism is studied in the two-leg S=1/2 ladder. We develop an exact spin-chirality duality transformation, under which the system is self-d…

Ground-State Phase Diagram of Frustrated Anisotropic Quantum Spin Chains
T. Hikihara, M. Kaburagi, H. Kawamura
Recent studies on the frustrated quantum spin chains with easy-plane anisotropy are reviewed. We are particularly interested in novel "chiral" phases characterized by the spontaneo…

Ground-State Phase Diagram of Frustrated Antiferromagnetic S=1 Chain with Uniaxial Single-Ion-Type Anisotropy
Toshiya Hikihara
The ground-state phase diagram of a frustrated S=1 Heisenberg spin chain with uniaxial single-ion-type anisotropy is studied using the infinite-system density-matrix renormalizatio…
