摘要：

Correlation functions play an important role in determining the structural and energetic properties of electronic systems. However, exact results are available only for ideal systems free of electrostatic interactions. Here we present a liquid-state method that combines classical mapping of the Pauli exclusion principle with the universality ansatz of the bridge functional. We show excellent agreement of the new method with quantum Monte Carlo simulation for predicting the electronic correlation functions and thermodynamic properties of uniform electron systems.
