An Explicitly Connected Many-Body Perturbation Theory for Incomplete Model Spacefunctions have the product-separability. Starting from the earliest work of Brandow, almost all the later developments classified the orbital basis into “core”, “particle” and “valence” orbitals, and the model space was taken to contain determinants with completely filled core orbitals and pa

Quantum Fluid Dynamics: An Extended Coupled Cluster Treatmentmore, we show how these are also exactly satisfied by most practical approximation schemes applied to the otherwise exact ECCM description. The fact that the ECCM amplitudes all strictly obey the cluster property, further implies that our gauge-invariant formalism is capable in principle of a comple

0342-4901 ems, Calcutta, February 1 - 10, 1988. The organizers invited leading experts to present recent developments of many-body methods as applied to molecules and condensed systems. The panorama portrayed is quite broad, but by no means exhaustive. The emphasis is undoubtedly on a "molecular point of view

For the EE calculation the model space is constructed from all particle-hole excitations obtained from the IP/EA active orbitals. Results using the MRCCSD approximation are presented and compared to results obtained from CI, MCSCF, GF, single-reference CC calculations, and experiment.

Marsha van Oostwaard,Andréa Marquesse only the first order correction, which involves a sum over all excited RPA states, gives an appreciable correction to the state representation of the transition probability. Parallel conclusions are obtained in both the dipole length and the dipole velocity formulation.

SAC-CI Calculations of the Excited and Ionized States of Conjugated Moleculesroblem in the theory of excited states: the difficulty in the reliable description of the so called V-type excited states of conjugated molecules. Systematic assignments are also given to other valence and Rydberg excited states and ionized states.
