    "abstract": "We show how many-body ground state entanglement information may be extracted\nfrom sub-system energy measurements at zero temperature. A precise relation\nbetween entanglement and energy fluctuations is demonstrated in the weak\ncoupling limit. Examples are given with the two-state system and the harmonic\noscillator, and energy probability distributions are calculated. Comparisons\nmade with recent qubit experiments show this type of measurement provides\nanother method to quantify entanglement with the environment.",
