Hybrid Treatments Based on Determinant Seniority Numbers and Spatial Excitation Levels in the Configuration Interaction Framework
(Elsevier Academic Press Inc, 2018-01)
In this work we project the Hamiltonian of an N-electron system onto a set of N-electron determinants cataloged by their seniority numbers and their excitation levels with respect to a reference determinant. We show that, ...
Non-linear energy harvesting system efficiency comparison from periodic to non-ideal excitation
(2014-01-01)
Dynamics of a non-linear energy harvesting is affected by excitation source and to explore efficiency it is necessary to understand which region offers more energy and the influence of a forced periodic vibration related ...
A hybrid configuration interaction treatment based on seniority number and excitation schemes
(American Institute Of Physics, 2014-12)
We present a configuration interaction method in which the Hamiltonian of an N-electron system is projected on Slater determinants selected according to the seniority-number criterion along with the traditional excitation-based ...
Electron-impact excitation of H-2: minimal orbital basis for single configuration interaction
(Iop Publishing LtdBristolInglaterra, 2004)
Spin contamination-free N -electron wave functions in the excitation-based configuration interaction treatment
(American Institute of Physics, 2016-07)
This work deals with the spin contamination in N-electron wave functions provided by the excitation-based configuration interaction methods. We propose a procedure to ensure a suitable selection of excited N-electron Slater ...
Nonlinear identification of mooring lines in dynamic operation of floating structures
(Elsevier, 2004-12)
An adaptive algorithm for on-line estimation of physical coefficients of cables in viscous environment is presented. The procedure is useful for obtaining cable characteristics, which are needed in stability analysis and ...
Importance of considering helium excited states in He + scattering by an aluminum surface
(American Physical Society, 2014-11)
The He+/Al system is a very interesting projectile-surface combination which was thought initially as an example of a pure Auger neutralization mechanism. Then, because of the measured reionization explained by the antibonding ...
Towers of positive parity excited baryons and their mixing in the large Nc limit
(American Physical Society, 2017-05)
We consider configuration mixing for the nonstrange positive parity excited baryons in the [56′,0+], [56,2+], [70,0+], and [70,2+] quark model SU(6)×O(3) multiplets contained in the N=2 band. Starting from the effective ...
