Spin-Orbital Entanglement and Phase Diagram of Spin-orbital Chain with Symmetry
Yan Chen, Z. D. Wang, Y. Q. Li +1
Spin-orbital entanglement in quantum spin-orbital systems is quantified by a reduced von Neumann entropy, and is calculated for the ground state of a coupled spin-orbital chain wit…

Rigorous results for a hierarchy of generalized Heisenberg models
You-Quan Li
The Lieb-Schultz-Mattis theorem is extended to generalized Heisenberg models related to non-exceptional Lie algebras. It is shown that there are no energy gaps above the ground sat…
