Topological Phases of the Spin-1/2 Ferromagnetic-Antiferromagnetic Alternating Heisenberg Chain with Frustrated Next-Nearest-Neighbour Interaction
Kazuo Hida, Ken'ichi Takano, Hidenori Suzuki
The spin-1/2 ferromagnetic-antiferromagnetic alternating Heisenberg chain with ferromagnetic next-nearest-neighbour (NNN) interaction is investigated. The ground state is the Halda…
Haldane Phases and Ferrimagnetic Phases with Spontaneous Translational Symmetry Breakdown in Distorted Mixed Diamond Chains with Spins 1 and 1/2
Kazuo Hida, Ken'ichi Takano, Hidenori Suzuki
The ground states of two types of distorted mixed diamond chains with spins 1 and 1/2 are investigated using exact diagonalization, DMRG, and mapping onto low-energy effective mode…
Scaling Property of the F-AF Spin Chain Near the Exactly Solvable Point
H. Suzuki, K. Takano
We investigate the ground state of the - spin-1/2 chain with and in the case that the nearest-neighbor interaction in the -direction has a weak a…
Quantum Phase Transitions in Alternating-Bond Mixed Diamond Chains with Spins 1 and 1/2
Kazuo Hida, Ken'ichi Takano, Hidenori Suzuki
We investigate the mixed diamond chain composed of spins 1 and 1/2 when the exchange interaction is alternatingly distorted. Depending on the strengths of frustration and distortio…
Melting Temperature of Metals Based on the Nearly Free Electron Model
Tamifusa Matsuura, Hidenori Suzuki, Ken'ichi Takano +1
We propose a general formula for the melting temperature of metals in terms of electronic mass, electronic number, and nearest-neighbor lattice distance. We derive it from the inst…
Finite Temperature Properties of the Mixed Diamond Chain with Spins 1 and 1/2
Kazuo Hida, Ken'ichi Takano, Hidenori Suzuki
We formulate statistical mechanics for the mixed diamond chain with spins of magnitudes 1 and 1/2. Owing to a series of conservation laws, any eigenstate of this system is decompos…
Exact spin-cluster ground states in a mixed diamond chain
Ken'ichi Takano, Hidenori Suzuki, Kazuo Hida
The mixed diamond chain is a frustrated Heisenberg chain composed of successive diamond-shaped units with two kinds of spins of magnitudes S and S/2 (S: integer). Ratio of…
Exact degenerate ground states for the F-AF spin chain with bond alternation
Hidenori Suzuki, Ken'ichi Takano
We investigate the - spin chain consisting of spins with magnitude . The nearest-neighbor and the next-nearest-neighbor exchange interactions are ferromagnetic a…
