Reduced density matrix functional theory at finite temperature. III.
Application to the electron gas: Correlation effects

Tim Baldsiefen, E. K. U. Gross
Based on our derivation of finite temperature reduced density matrix functional theory and the discussion of the performance of its first-order functional this work presents several different correlation-energy functionals and applies them to the homogeneous electron gas. The zero temperature limits of the correlation-energy and the momentum distributions are investigated and the magnetic phase diagrams in collinear spin configuration are discussed.
