Quantum Entanglement in the Two Impurity Kondo Model
Sam Young Cho, Ross H. McKenzie
In order to quantify quantum entanglement in two impurity Kondo systems, we calculate the concurrence, negativity, and von Neumann entropy. The entanglement of the two Kondo impuri…

Anomalous Excitation Spectra of Frustrated Quantum Antiferromagnets
Weihong Zheng, John O. Fjaerestad, Rajiv R. P. Singh +2
We use series expansions to study the excitation spectra of spin-1/2 antiferromagnets on anisotropic triangular lattices. For the isotropic triangular lattice model (TLM) the high-…
