Inversion Phenomena of the Anisotropies of the Hamiltonian and the Wave Function in Quantum Spin Chains
Kiyomi Okamoto
We investigate the inversion phenomena between the XXZ anisotropies of the Hamiltonian and the wave function in quantum spin chains. We focus on the S=1/2 geometrically frustrated…

Quantum phase transitions of the asymmetric three-leg spin tube
Tôru Sakai, Masahiro Sato, Kouichi Okunishi +3
We investigate quantum phase transitions of the S=1/2 three-leg antiferromagnetic spin tube with asymmetric inter-chain (rung) exchange interactions. On the basis of the electron t…
