Title: Natural Thermal and Magnetic Entanglement in the 1D Heisenberg Model

Journal Article · · Physical Review Letters

We investigate the entanglement between any two spins in a one dimensional Heisenberg chain as a function of temperature and the external magnetic field. We find that the entanglement in an antiferromagnetic chain can be increased by increasing the temperature or the external field. Increasing the field can also create entanglement between otherwise disentangled spins. This entanglement can be confirmed by testing Bell{close_quote}s inequalities involving any two spins in the solid.
