    "abstract": "We investigate the entanglement between any two spins in a one dimensional\nHeisenberg chain as a function of temperature and the external magnetic field.\nWe find that the entanglement in an antiferromagnetic chain can be increased by\nincreasing the temperature or the external field. Increasing the field can also\ncreate entanglement between otherwise disentangled spins. This entanglement can\nbe confirmed by testing Bell\u0027s inequalities involving any two spins in the\nsolid.",
