Twist Boundary Conditions of Quantum Spin Chains near the Gaussian Fixed Points
A. Kitazawa
Duality transformation, which relates a high-temperature phase to a low-temperature one, is used exactly to determine the critical point for several models (2D Ising, Potts, Ashkin…

Level spectroscopy II - application to the Gaussian model -
Kiyohide Nomura, Atsuhiro Kitazawa
It was a difficult problem to determine the Gaussian fixed line from the numerical data, because close to the Berezinskii-Kosterlitz-Thouless multicritical point the divergence of…

Phase Diagram of Bond-Alternating XXZ chains
Atsuhiro Kitazawa, Kiyohide Nomura, Kiyomi Okamoto
The phase transitions between the XY, the dimer and the Haldane phases of the spin-1 bond-alternating XXZ chain are studied by the numerical diagonalization. We determine the phase…
