A study of the compactness of wave functions based on Shannon entropy indices: a seniority number approach
(Springer, 2015-07)
This work reports the formulation of Shannon entropy indices in terms of seniority numbers of the Slater determinants expanding an N-electron wave function. Numerical determinations of those indices prove that they provide ...
Seniority number in spin-adapted spaces and compactness of configuration interaction wave functions
(American Institute of Physics, 2013-08-23)
This work extends the concept of seniority number, which has been widely used for classifying N-electron Slater determinants, to wave functions of N electrons and spin S, as well as to N-electron spin-adapted Hilbert ...

Quantum entanglement of helium-like systems with varying-Z: Compact state-of-the-art CI wave functions
(Iop Publishing, 2015-07-17)
In this work we have performed state-of-the-art configuration-interaction (CI) calculations to determine the linear and von Neumann entanglement entropies for the helium-like systems with varying nuclear charge Z in the ...
A GRADIENT-LIKE NONAUTONOMOUS EVOLUTION PROCESS
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2010)
In this paper we consider a dissipative damped wave equation with nonautonomous damping of the form u(tt) + beta(t)u(t) - Delta u + f(u) (1) in a bounded smooth domain Omega subset of R(n) with Dirichlet boundary conditions, ...
