Spin-Peierls transition to a Haldane phase
Hironori Yamaguchi, Hiroki Takahashi, Takashi Kawakami +4
We present an organic compound exhibiting a spin-Peierls (SP) transition to an effective spin-1 antiferromagnetic uniform chain, that is, the Haldane chain. The clear disappearance…
Spin Nematic Liquid of the Distorted Diamond Spin Chain in Magnetic Field
Tôru Sakai, Hiroki Nakano, Rito Furuchi +1
The magnetization process of the distorted diamond spin chain with the anisotropic ferromagnetic interaction is investigated using the numerical diagonalization of finite-s…
Numerical Study of S=1/2 Heisenberg Antiferromagnet on the Floret Pentagonal Lattice
Rito Furuchi, Hiroki Nakano, Toru Sakai
The Heisenberg antiferromagnet on the floret-pentagonal lattice with two kinds of interaction strength is studied by the numerical-diagonalization method. It is known that,…
Large-Scale Numerical-Diagonalization Study of the Shastry-Sutherland Model
Hiroki Nakano, Toru Sakai
The Heisenberg antiferromagnet on the orthogonal-dimer lattice (Shastry-Sutherland model) is studied by the Lanczos diagonalization method. The properties of this model are…
Field-Induced Spin Nematic Liquid of the Bond-Alternating Chain with the Anisotropy
Ryosuke Nakanishi, Takaharu Yamada, Rito Furuchi +5
The ferromagnetic-antiferromagnetic bond-alternating spin chain with the anisotropy on the ferromagnetic exchange interaction in magnetic field is investigated using the nu…
Nematic Tomonaga-Luttinger Liquid Phase in an Ferromagnetic-Antiferromagnetic Bond-Alternating Chain
Takashi Tonegawa, Kiyomi Okamoto, Kiyohide Nomura +1
We numerically investigate the ground-state phase diagram of the ferromagnetic-antiferromagnetic bond-alternating chain, in which the ferromagnetic interactions are stronge…
