Analytic structure of thermodynamic systems with repulsive interactions
Analytic structure of thermodynamic systems with repulsive interactions
Thermodynamic properties of systems with repulsive interactions are considered in the grand-canonical ensemble. The analytic structure of the excluded-volume model in the complex plane of the system chemical potential (fugacity) is elaborated, based on the fact that the pressure function can be given in terms of the Lambert $W$ function. …
