Correlation Effects in Many-Fermion Systems: Multiple-Particle Excitation Expansion
Correlation Effects in Many-Fermion Systems: Multiple-Particle Excitation Expansion is a scholarly work, published in 1963 in ''Physical Review''. The main subjects of the publication include ground state, wave function, high temperature superconductor, excitation, quantum electrodynamics, physics, many-body theory, perturbation theory, fermion, ultracold atom, quantum mechanics, density functional theory, perturbation, many-body problem, and statistical physics. The ground-state wave function and energy of a finite system of interacting fermions are expanded in terms of multiple-particle excitations on an uncorrelated zero-order state.
