Local correlation energies of two-electron atoms and model systems
We present nearly local definitions of correlation energy density, and its potential and kinetic components, and evaluate them for several two-electron systems. This information should provide valuable guidance in constructing better correlation functionals than those in common use. In addition, we demonstrate that the quantum chemistry and the density-functional definitions of the correlation ...
متن کاملDynamics of Entanglement for Two-Electron Atoms
Abstract We studied the dynamics of the entanglement for two electron atoms as a ”bipartite” quantum system with continuous degrees of freedom. We analyze in particular the time evolution of initial states created from a superposition of the eigenstates of the two-electron Hamiltonian with variable nuclear charge Z. We find that the pairwise entanglement for the two electrons propagate in a way...

متن کاملTwo-electron photoionization of endohedral atoms
Using He@C60 as an example, we demonstrate that static potential of the fullerene core essentially alters the cross section of the two-electron ionization differential in one-electron energy dσ++(ω)/dε. We found that at high photon energy prominent oscillations appear in it due to reflection of the second, slow electron wave on the C60 shell, which ”dies out” at relatively high ε values, of abo...
متن کاملVariational Two-electron Reduced Density Matrix Theory for Many-electron Atoms and Molecules: Implementation of the Spin- and Symmetry-adapted T2 Condition through First-order Semidefinite Programming
Abstract The energy and properties of a many-electron atom or molecule may be directly computed from a variational optimization of a two-electron reduced density matrix (2-RDM) that is constrained to represent many-electron quantum systems. In this paper we implement a variational 2-RDM method with a representability constraint, known as the T2 condition. The optimization of the 2-RDM is perfor...
