A study of trapped Bose gas beyond mean-field theory
Arup Banerjee, Manoranjan P. Singh
We study the ground-state properties of dilute Bose gas confined to both isotropic and anisotropic traps to assess the accuracy of Gross-Pitaevskii (GP) theory. To go beyond GP app…

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…

Hydrodynamic approach to TDDFT; response properties of metal clusters
Arup Banerjee, Manoj K. Harbola
Performing electronic structure calculations for large systems, such as nanoparticles or metal clusters, via orbital based Hartree-Fock or Kohn-Sham theories is computationaly dema…
