Exact correlations in the Lieb-Liniger model and detailed balance out-of-equilibrium
We study the density-density correlation function of the 1D Lieb-Liniger model and obtain an exact expression for the small momentum limit of the static correlator in the thermodynamic limit. We achieve this by summing exactly over the relevant form factors of the density operator in the small mo...
