Summary: The statistical notion of disequilibrium (\(D\)) was introduced by \textit{R. L??pez-Ruiz} et al. [``A statistical measure of complexity'', Phys. Lett., A 209, No. 5--6, 321--326 (1995; \url{doi:10.1016/0375-9601(95)00867-5})] more than 20 years ago. \(D\) measures the amount of ``correlational structure'' of a system. We wish to use \(D\) to analyze one of the simplest types of quantum correlations, those present in gaseous systems due to symmetry considerations. To this end, we extend the LMC formalism to the grand canonical environment and show that \(D\) displays distinctive behaviors for simple gases, that allow for interesting insights into their structural properties.
