    "abstract": "We show that macroscopic thermodynamical properties - such as functions of\ninternal energy and magnetization - can detect quantum entanglement in solids\nat nonzero temperatures in the thermodynamical limit. We identify the parameter\nregions (critical values of magnetic field and temperature) within which\nentanglement is witnessed by these thermodynamical quantities.",
