Quantum nonlocality of Heisenberg XX model with Site-dependent Coupling
Strength
Chunfeng Wu, Jing-Ling Chen, D. M. Tong, L. C. Kwek, C. H. Oh
abstract: We show that the generalized Bell inequality is violated in the extended
Heisenberg model when the temperature is below a threshold value. The threshold
temperature values are obtained by constructing exact solutions of the model
using the temperature-dependent correlation functions. The effect due to the
presence of external magnetic field is also illustrated.
