Spin-Wave Description of Haldane-gap antiferromagnets
Shoji Yamamoto, Hiromitsu Hori
Modifying the conventional antiferromagnetic spin-wave theory which is plagued by the difficulty of the zero-field sublattice magnetizations diverging in one dimension, we describe…

Quantum and thermal phase transitions in the Bechgaard salts and their analogs
Hiromitsu Hori, Shoji Yamamoto
In order to investigate quantum and thermal phase transitions in the Bechgaard salts and their sulfur analogs, we perform finite-temperature Hartree-Fock calculations in one dimens…
