Bifurcation at the c=3/2 Takhtajan-Babujian point to the c=1 critical lines
Atsuhiro Kitazawa, Kiyohide Nomura
We study the S=1 quantum spin chains with bilinear, biquadratic, plus bond alternation in the vicinity of the S=1 Takhtajan-Babujian model. Transition line between the Haldane and…

Magnetization plateau and quantum phase transition of the S=1/2 trimerized XXZ spin chain
Kiyomi Okamoto, Atsuhiro Kitazawa
We study the plateau of the magnetization curve at ( is the saturation magnetization) of the trimerized spin chain. By examining the leve…
