Density functional theory calculation of ground state energy, dipole polarizability and hyperpolarizability of a confined helium atom
Subhajit Waugh, Avijit Chowdhury, Arup Banerjee
We calculate ground-state energies and densities of a helium atom confined in an impenetrable spherical box within density functional theory. These calculations are performed by va…

Calculation of ground- and excited-state energies of confined helium atom
Arup Banerjee, C. Kamal, Avijit Chowdhury
We calculate the energies of ground and three low lying excited states of confined helium atom centered in an impenetrable spherical box. We perform the calculation by employing va…

Frequency dependent hyperpolarizabilities of atoms; calculations using density-functional theory
Arup Banerjee, Manoj K. Harbola
Using the orbitals generated by the van Leeuwen-Baerends potential, we calculate frequency dependent response properties of noble gas atoms of He, Ne and Ar and alkaline earth atom…
