Classes of exact wave functions for general time-dependent Dirac Hamiltonians in 1+1 dimensions
(2003-05-01)
The construction of two classes of exact solutions for the most general time-dependent Dirac Hamiltonian in 1+1 dimensions was discussed. The extension of solutions by introduction of a time-dependent mass was elaborated. ...

New approach for approximating the continuum wave function by Gaussian basis set
(Elsevier Science, 2012-12)
A new approach for approximating the continuum wave functions for hydrogenic atoms with Gaussians basis sets is developed and tested. In this the plane wave is left unchanged and the distorting factor, represented by the ...
Configuration interaction wave functions: A seniority number approach
(American Institute of Physics, 2014-06)
This work deals with the configuration interaction method when an N-electron Hamiltonian is projected on Slater determinants which are classified according to their seniority number values. We study the spin features of ...
The linear combination of vibrational wave functions (lcvw) method in a morse-gaussian double well molecular potential
(BALTZER SCIENCE PUBLISHERS, 2006)
An information-theoretic resolution of the ambiguity in the local hardness
(Royal Society of Chemistry, 2014)
The ambiguity of the local hardness is resolved by using information theory to select definitions of the local hardness that are as close as possible to a well-defined approximate formula for the local hardness. A condensed ...
Variational calculation of positronium-helium-atom scattering length
(2001-08-01)
A basis-set calculation scheme for S-waves Ps-He elastic scattering below the lowest inelastic threshold was formulated using a variational expression for the transition matrix. The scheme was illustrated numerically by ...
