Ground-State and Thermodynamic Properties of the Quantum Mixed Spin-1/2-1/2-1-1 Chain
Takashi Tonegawa, Toshiya Hikihara, Makoto Kaburagi +3
We investigate both analytically and numerically the ground-state and thermodynamic properties of the quantum mixed spin-1/2-1/2-1-1 chain described by the Hamiltonian $H=\sum_{\el…
One-dimensional Heisenberg antiferromagnet in which two S=1/2 and two S=1 spins are arranged alternatively
T. Tonegawa, T. Hikihara, T. Nishino +3
Ground-state and thermodynamic properties of the one-dimensional Heisenberg antiferromagnet in which two S=1/2 and two S=1 spins are arranged alternatively are studied by a quantum…
Low-Lying Excitations in the S=1 Antiferromagnetic Heisenberg Chain
Shoji Yamamoto, Seiji Miyashita
In order to confirm the picture of domain-wall excitations in the hidden antiferromagnetic order of the Haldane phase, the structure of the low-lying excitations in the S=1 antifer…
Nontrivial resonance of nanoscale uniaxial magnets to alternating field
Seiji Miyashita, Keiji Saito, Hans De Raedt
How nanoscale uniaxial magnets respond to an alternating field is studied by direct numerical calculation. A nontrivial oscillation of the magnetization is found, which is analyzed…
