Field-induced incommensurate order for the quasi-one-dimensional XXZ model in a magnetic field
Kouichi Okunishi, Takahumi Suzuki
We investigate phase transitions of the quasi-one-dimensional XXZ model in a magnetic field, using the bosonization combined with the mean field treatment of the inter-chain intera…
NMR relaxation of quantum spin chains in magnetic fields
Takahumi Suzuki, Sei-ichiro Suga
We investigate NMR relaxation rates 1/T_1 of quantum spin chains in magnetic fields. Universal properties for the divergence behavior of 1/T_1 are obtained in the Tomonaga-Luttinge…
Supersolid of Hardcore Bosons on the Face Centered Cubic Lattice
Takahumi Suzuki, Naoki Kawashima
We investigate a supersolid state in hardcore boson models on the face-centered-cubic (FCC) lattice. The supersolid state is characterized by a coexistence of crystalline order and…
Tomonaga-Luttinger Liquid in a Quasi-One-Dimensional S=1 Antiferromagnet Observed by the Specific Heat
M. Hagiwara, H. Tsujii, C. R. Rotundu +6
Specific heat experiments on single crystals of the S=1 quasi-one-dimensional bond-alternating antiferromagnet Ni(C_9H_24N_4)(NO_2)ClO_4, alias NTENP, have been performed in magnet…
Dynamical properties of S=1 bond-alternating Heisenberg chains in transverse magnetic fields
Takahumi Suzuki, Sei-ichiro Suga
We calculate dynamical structure factors of the S=1 bond-alternating Heisenberg chain with a single-ion anisotropy in transverse magnetic fields, using a continued fraction method…
Dynamical properties of S=1 bond-alternating Heisenberg chains at finite temperatures
Takahumi Suzuki, Sei-ichiro Suga
Dynamical structure factors of the S=1 bond-alternating spin chains in the dimer phase are calculated at finite temperature, using the pair dynamical correlated-effective-field app…
