Part of the Mathematical Physics Studies book series (MPST)


The Quantum Cluster Equilibrium model which has been developed within the past two decades is presented. It constitutes an alternative for the investigation of fluid phases and phase transitions. In that contribution, a conceptual overview is given. It is explained, how a limited number of molecular clusters is employed for the description of the liquid phase and the computation of thermodynamic properties. Herein, high-level electronic structure methods may be transferred to macroscopic phases via statistical mechanics. The suggested method is employed so that liquid water may be treated at the coupled-cluster level including single, double and perturbative triple excitations.
