Single-copy entanglement and entanglement spectrum in spin chains — •Masudul Haque and Andreas Lauchli — Max Planck Institute for Physics of Complex Systems, Dresden, Germany

Features of many-particle physics are often manifested in the entanglement between two parts of a condensed-matter system. The entanglement can be characterized by, e.g., the reduced entropy, the single-copy entanglement, or the complete entanglement spectrum.

I will present results on these quantities in several prominent 1D models of quantum magnetism, namely, the XXZ model, the Majumdar-Ghosh chain, and the spin-1 bilinear-biquadratic chain.
