Calculation of van der Walls coefficients of alkali metal clusters by hydrodynamic approach to time-dependent density-functional theory
Arup Banerjee, Manoj K. Harbola
In this paper we employ the hydrodynamic formulation of time-dependent density functional theory to obtain the van der Waal coefficients and of alkali-metal cluster…
Comment on relationship between atomic squeezed and entangled states
Arup Banerjee
The ability of parameter recently proposed by Sorensen et al. (Nature, 409, 63 (2001)) to characterize entanglement or inseparability is investigated for a system of two two-level…
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…
