Measuring Entropy and Short-Range Correlations in the Two-Dimensional Hubbard Model
We measure entropy and short-range correlations of ultracold fermionic atoms in an optical lattice for a range of interaction strengths, temperatures, and fillings. In particular, we extract the mutual information between a single lattice site and the rest of the system from a comparison between the...
