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…
