Study of the RPA pair correlation function in GaAs-AlGaAs parabolic quantum well wires

Resumo

The ground state intrasubband pair-correlation function for a quasi-one-dimensional electron gas confined in a GaAs-AlxGa1¡xAs parabolic quantum well wire within the Random-Phase Approximation (RPA) is calculated. We have considered two wires with subband energies separation ~­ = 2:0 meV and ~­ = 2:5 meV. The dependence of the pair-correlation function on the electronic density was studied and the regions where the RPA approach cannot be used were precisely determined.
