    "abstract": "Some thermodynamical properties of solids, such as heat capacity and magnetic\nsusceptibility, have recently been shown to be linked to the amount of\nentanglement in a solid. However this entanglement may appear a mere\nmathematical artifact of the typical symmetrization procedure of many-body wave\nfunction in solid state physics.\n  Here we show that this entanglement is physical demonstrating the principles\nof its extraction from a typical solid state system by scattering two particles\noff the system. Moreover we show how to simulate this process using present-day\noptical lattices technology. This demonstrates not only that entanglement\nexists in solids but also that it can be used for quantum information\nprocessing or for test of Bell\u0027s inequalities.",
