## Quantum correlations in a few-atom spin-1 Bose-Hubbard modelÇakmak, Barış and Karpat, Göktuğ and Gedik, Zafer (2012)
## AbstractWe study the thermal quantum correlations and entanglement in spin-1 Bose-Hubbard model with two and three particles. While we use negativity to calculate entanglement, more general non-classical correlations are quantified using a new measure based on a necessary and sufficient condition for zero-discord state. We demonstrate that the energy level crossings in the ground state of the system are signalled by both the behavior of thermal quantum correlations and entanglement.
