Entanglement, quantum phase transition, and scaling in the<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>XXZ</mml:mi></mml:math>chain
Motivated by recent development in quantum entanglement, we study relations among concurrence C, ${\mathrm{SU}}_{q}(2)$ algebra, quantum phase transition and correlation length at the zero temperature for the $\mathrm{XXZ}$ chain. We find that at the SU(2) point, the ground state possesses the maximum concurrence. When the anisotropic parameter $\ensuremath{\Delta}$ is deformed, …
