Potential Functions of Al2 by the Relativistic Fock- Space Coupled Cluster Method
Potential functions of the ground and low excited states of Al2 are calculated by the relativistic Fock-space coupled cluster method in the framework of the projected Dirac-Coulomb Hamiltonian. A moderate-size basis [16s11p3d3f/6s6p3d2f ] is used. Πu is confirmed as the ground state of the system. Its spin orbit splittings are reproduced well, with the Λ = 1, 2 states lying 32.5 and 66.1 cm−1, ...
متن کاملBrillouin–Wigner coupled cluster theory: Fock-space approach
The generalization of coupled cluster ~CC! theory is far from being a standard method to account for correlation effects of ubiquitous open-shell systems. This dilemma is largely due to three problems. The first concerns the incorporation of multiple reference ‘‘guess’’ wave functions into nonvariational theories. Next is the size-extensivity issue. Finally, and perhaps most importantly is the ...
متن کاملInteracting Fock Space versus Full Fock Module*
We present several examples where moments of creators and annihilators on an interacting Fock space may be realized as moments of creators and annihilators on a full Fock module. Motivated by this experience we answer the question, whether such a possibility exists for arbitrary interacting Fock spaces, in the affirmative sense. We treat the problem in full algebraic generality. As a by-product...
متن کاملFock Space Representations in Neural Field Theories
We outline a computational model of syntactic language processing based on Smolensky’s Fock space representations of symbolic expressions using spherical wave functions. Symbolic computation, regarded as nonlinear operators acting upon these waves, provides a discrete sequence of training patterns that could be used to solve the inverse problem of neural field theories in order to determine the...
متن کاملQuantum Field Theory on Fock Projective Space
It is shown that some analog of the “second quantization” exists in the framework of CP (N) theory. I analyse conditions under that “geometrical bosons” may be identified with real physical fields. The compact character of a state manifold should preserve the quantities of dynamical variables from divergences.
