A simple approximation beyond Hartree - Fock
The form of a real AT-body fermion wave function when expanded in Slater determinants of natural orbitals is investigated using a computer. I t is found that in the case when the number of natural orbitals is N f 2 there is a considerable reduction in the number of Slater determinants required. This offers the possibility of calculating atomic wave functions which are significantly more accurat...
متن کاملOne new species and three new records of Chrysis Linnaeus from China (Hymenoptera, Chrysididae)
Four Chinese Chrysis species-groups, the antennata, capitalis, elegans, and maculicornis species-groups, are discussed. Chrysis lapislazulina Rosa & Xu, sp. n. is described in the elegans species-group; and three species, C. brachyceras Bischoff, 1910, C. subdistincta Linsenmaier, 1968 and C. yoshikawai Tsuneki, 1961, are reported for the first time from China in other species-groups. A new syn...
متن کاملA sparse algorithm for the evaluation of the local energy in quantum Monte Carlo
A new algorithm is presented for the sparse representation and evaluation of Slater determinants in the quantum Monte Carlo (QMC) method. The approach, combined with the use of localized orbitals in a Slater-type orbital basis set, significantly extends the size molecule that can be treated with the QMC method. Application of the algorithm to systems containing up to 390 electrons confirms that...
متن کاملSLAC-PUB-747 May 1970 (TH) METHODS I?OR THE I~ETlIE-SRLP~~TER EQUATION I: SPECIAL FUNCTIONS AND EXPANSIONS IN SPHERICAL HARMONICS*
Elements of the structure of the Bethe-Salpeter equation are studied. Properties of useful special functions are obtained and free particle solutions to the truncated expansion of the equation in four-dimensional spherical harmonics are derived in terms of known special functions. Validity of the truncation approximation is examined in terms of a convenient representation of the Green’s functio...
متن کاملSLAC-PUB-748 May 1970 VW METHODS FOR THE BETHE-SALPETER EQUATION II: BRACKETS AND THE N/D.METHOD*
A systematic study of the Bethe-Salpeter relativistic two-body equation is continued. The equation is treated in Wick-rotated coordinate space. A bilinear combination of functions, called a bracket ii defined. Its relation to scattering amplitudes and their residues at poles, and to questions of structure of the equation and numerical accuracy of solutions is developed. N and D matrices similar...
