Frustration Induced Quantum Phases in Mixed Spin Chain with Frustrated Side Chains
Kazuo Hida, Ken'ichi Takano
A mixed Heisenberg spin chain with frustrated side chains is investigated by numerical and perturbational calculations. A frustration-induced quantum partially polarized ferrimagne…
Disordered ground states in a quantum frustrated spin chain with side chains
Ken'ichi Takano, Kazuo Hida
We study a frustrated mixed spin chain with side chains, where the spin species and the exchange interactions are spatially varied. A nonlinear sigma model method is formulated for…
Emergence of Long Period Antiferromagnetic Orders from Haldane Phase in S=1 Heisenberg Chains with D-Modulation
Kazuo Hida, Wei Chen
The effect of spatial modulation of the single-site anisotropy D on the ground state of the S=1 Heisenberg chains is investigated. In the case of period 2 modulation, it is found t…
Quantum vs. Classical Magnetization Plateaus of S=1/2 Frustrated Heisenberg Chains
Kazuo Hida, Ian Affleck
The competition between quantum and classical magnetization plateaus of S=1/2 frustrated Heisenberg chains with modified exchange couplings is investigated. The conventional S=1/2…
Real Space Renormalization Group Study of the S=1/2 XXZ Chains with Fibonacci Exchange Modulation
Kazuo Hida
Ground state properties of the S=1/2 antiferromagnetic XXZ chain with Fibonacci exchange modulation are studied using the real space renormalization group method for strong modulat…
New Universality Class in the S=1/2 Fibonacci Heisenberg Chains
Kazuo Hida
Low energy properties of the S=1/2 antiferromagnetic Heisenberg chains with Fibonacci exchange modulation are studied using the real space renormalization group method for strong e…
