Spectroscopic structure of two interacting electrons in a quantum dot by the shifted 1 / N expansion method ” Omar Mustafa
نویسنده
چکیده
The shifted 1/N expansion technique (SLNT), used by El-Said (Phys. Rev. B 61, 13026 (2000)), to study the relative Hamiltonian of two interacting electrons confined in quantum dot, is investigated. It turned out that El-Said’s results from SLNT are unreliable and they are revised in this comment.

On the spectroscopic structure of two interacting electrons in a quantum dot
The shifted 1/N expansion technique used by El-Said (Phys. Rev. B 61, 13026 (2000)), to study the relative Hamiltonian of two interacting electrons confined in a quantum dot, is investigated. El-Said’s results from SLNT are revised and results from an alternative method are also reported. The distinctive role of the central spike term, (m − 1/4)/q, in determining spectral properties of the abov...

متن کاملOn the correlation energies for two interacting electrons in a parabolic quantum dot
The correlation energies for two interacting electrons in a parabolic quantum dot are studied via a pseudo-perturbation recipe. It is shown that the central spike term, (m2 −1/4)/r2, plays a distinctive role in determining the spectral properties of the above problem. The study is carried out for a wide range of the Coulomb coupling strength λ relative to the confinement.
متن کاملEffect of asymmetric quantum dot rings in electron transport through a quantum wire
The electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting Hamiltonian Anderson tunneling method. In this paper we concentrate on the configuration of the quantum dot rings. We show that the asymmetric structure of QD-scatter system strongly influences the amplitude an...
