Entanglement in a Quantum Mixed-Spin Chain
arXiv:quant-ph/0605063 · doi:10.1016/j.physleta.2007.01.053
Abstract
The entanglement in a general mixed spin chain with arbitrary spin and 1/2 is investigated in the thermodynamical limit. The entanglement is witnessed by the magnetic susceptibility which decides a characteristic temperature for an entangled thermal state. The characteristic temperature is nearly proportional to the interaction and the mixed spin . The bound of negativity is obtained on the basis of the magnetic susceptibility. It is found that the macroscopic magnetic properties are affected by the quantum entanglement in the real solids. Meanwhile, the entanglement can be quantitatively evaluated by the thermodynamical observable.
