New biorthogonal potential–density basis functions

We use the weighted integral form of spherical Bessel functions, and introduce a new analytical set of complete and biorthogonal potential–density basis functions. The potential and density functions of the new set have finite central values and they fall off, respectively, similar to r and r at large radii where l is the latitudinal quantum number of spherical harmonics. The lowest order term ...

Basis Set Effects in Density Functional Calculations and BSSEcorrected on the Molybdate-Phosphonic acid Complex

In this research, this possibility was investigated the relative stablilty geometry and bindingenergies of the hydrogen bonds of Molybdate-Phosphonic Acid (MPA) complex in gas phase onthe basis of result of ab initio and DFT calculations. Three DFT methods have been applied forcalculations are B3LYP, BP86 and B3PW91 that have been studied in two series of basis sets:D95** and 6-31+G(d,p) for hy...

Kohn-Sham density-functional theory within a finite basis set

The Kohn-Sham self-consistent equations, urnig a finite orbital basis expansion, are formulated for exchangecodation functionals which depend on local densities and their gradients. It is shown that these can be solved iteratively without evaluation of density Hessians. A general expression is given for the energy gradient (with respect to nuclear motion) after self-consistency has been achieved.

Potential-Density Basis Sets for Galactic Disks

A class of complete potential-density basis sets in cylindrical (R,φ, z) coordinates is presented. This class is suitable for stability studies of galactic disks in three dimensions and includes basis sets tailored for disks with vertical density profiles that are exponential (e−|z|/z0), Gaussian (e−(z/z0) 2 ) or locally isothermal ( sech(z/z0) ). The basis sets are non-discrete and non-biortho...

A New Skew-normal Density

We present a new skew-normal distribution, denoted by NSN($lambada$). We first derive the density and moment generating function of NSN($lambada$). The properties of SN($lambada$), the known skew-normal distribution of Azzalini, and NSN($lambada$) are compared with each other. Finally, a numerical example for testing about the parameter $lambada$ in NSN($lambada$) is given. ...
