The collective excitations of a two-dimensional electron gas (2 DEG) subjected to an arbitrary external confinement potential are studied using a density functional based, hydrodynamic theory. The equilibrium properties of the system are calculated in the spirit of the Thomas-Fermi-Dirac approximation ...
The errors in the total energies using the Thomas-Fermi-Dirac-Weizsäcker formulation are approximately -0·4 per cent for Ne-Ne and -0·01 per cent for Ar-Ar molecules respectively. However, the values of the intermolecular potentials thus calculated are in general too negative and...
The Thomas–Fermi–Dirac-Weizscker model for finite temperature is presented. Starting with the free energy density, consistent expressions for the Helmholtz free energy, total energy, pressure and virial theorem are derived. The exchange and correlation terms are cast in a form that is suitable fo...
