Correlated basis function theory for fermion systems

摘要: A description of correlated basis function theory for Fermi systems is given with the perspective discussing some recent developments and its range applications. The actual status variational calculations in liquid helium, strongly electrons nuclear matter presented, by merits limitations most realistic trial wave functions. Correlated perturbation described as a tool to go beyond calculations. not-orthogonal newly developed orthogonal versions are discussed compared. brief review one-body Green’s calculation one main applications version theory. We describe generalized Hyper-Netted Chain scheme, showing that it constitutes powerful method compute hamiltonian identity operator matrix elements, which enter theory, starting from zeroth order or Such scheme sums up both reducible irreducible cluster terms, whereas original FHNC takes care terms only, particularly suitable state dependent correlations, well finite systems, like nuclei helium droplets.
