Theoretical analysis of the experiments on the double-spin-chain compound -- KCuCl
Tota Nakamura, Kiyomi Okamoto
We have analyzed the experimental susceptibility data of KCuCl and found that the data are well-explained by the double-spin-chain models with strong antiferromagnetic dimeriza…

Phase Diagram of S=1 Bond-Alternating XXZ Chains Reflecting the Hidden Z_2\times Z_2 Symmetry
Atsuhiro Kitazawa, Kiyohide Nomura
The phase diagram of the spin-1 bond-alternating XXZ chain is studied numerically. This model is appropriate to study the VBS picture and the hidden Z_2\times Z_2 symmetry concerni…

Haldane and dimer gap in general double spin-chain models
Tota Nakamura, Satoshi Takada, Kiyomi Okamoto +1
We have obtained an analytic expression for the dependence of excitation energy gap for an arbitrary double spin-chain by using the nonlocal unitary transformation and…
