Fourth-order perturbative extension of the single-double excitation coupled-cluster Part II: Angular reduction
نویسنده
چکیده
We tabulate angularly reduced fourth-order many-body corrections to matrix elements for univalent atoms, derived in [A. Emmons, Phys. Rev. A 65 , 052115 (2002)]. In particular we focus on practically important diagrams complementary to those included cluster method truncated at single and double excitations. Derivation and angular reduction of a large number of diagrams have the help of symbolic algebra software.

Fourth-order perturbative extension of the single-double excitation coupled-cluster method
Fourth-order many-body corrections to matrix elements for atoms with one valence electron are derived. The obtained diagrams are classified using coupled-cluster-inspired separation into contributions from n-particle excitations from the lowest-order wave function. The complete set of fourth-order diagrams involves only connected single, double, and triple excitations and disconnected quadruple...

The interaction of He with metastable CO(a P) gives rise to two adiabatic potential surfaces of reflection symmetry A8 and A9 which were calculated with the partially spin-restricted open-shell single and double excitation coupled cluster method with perturbative triples, RCCSD~T!. Two diabatic potentials were constructed and fitted analytically; the appropriate form of the angular expansion fu...
متن کاملSpin-orbit couplings within the equation-of-motion coupled-cluster framework: Theory, implementation, and benchmark calculations.
We present a formalism and an implementation for calculating spin-orbit couplings (SOCs) within the EOM-CCSD (equation-of-motion coupled-cluster with single and double substitutions) approach. The following variants of EOM-CCSD are considered: EOM-CCSD for excitation energies (EOM-EE-CCSD), EOM-CCSD with spin-flip (EOM-SF-CCSD), EOM-CCSD for ionization potentials (EOM-IP-CCSD) and electron atta...

Geometry optimization and harmonic vibrational frequency calculations have been carried out on the X̃(2)A(') state of P(2)H and the X̃(1)A(') state of P(2)H(-) using the restricted-spin coupled-cluster single-double plus perturbative triple excitation [RCCSD(T)] and explicitly correlated unrestricted-spin coupled-cluster single-double plus perturbative triple excitation [UCCSD(T)-F12x] methods.

A broadband Circuit Analogue (CA) absorber using double-circular-loop array is investigated in this paper. A simple equivalent circuit model is presented to accurately analyze this CA absorber. The circuit simulation of the proposed model agrees well with full-wave simulations. Optimization based the equivalent circuit model, is applied to design a single-layer circuit analogue absorber using d...
