Multichannel field-effect spin barrier selector
G. E. Marques, A. C. R. Bittencourt, C. F. Destefani +1
We have studied spin carrier dynamics under full spin-orbit coupling. The anisotropy of dispersions for independent circular spinor polarizations is explored as a possible vertical…
Spin-orbit coupling and magnetic spin states in cylindrical quantum dots
C. F. Destefani, S. E. Ulloa, G. E. Marques
We make detailed analysis of each possible spin-orbit coupling of zincblende narrow-gap cylindrical quantum dots built in two-dimensional electron gas. These couplings are related…
Restricted and unrestricted Hartree-Fock approaches for addition spectrum and Hund's rule of spherical quantum dots in a magnetic field
C. F. Destefani, J. D. M. Vianna, G. E. Marques
The Roothaan and Pople-Nesbet approaches for real atoms are adapted to quantum dots in the presence of a magnetic field. Single-particle Gaussian basis sets are constructed, for ea…
The violation of the Hund's rule in semiconductor artificial atoms
C. F. Destefani, J. D. M. Vianna, G. E. Marques
The unrestricted Pople-Nesbet approach for real atoms is adapted to quantum dots, the man-made artificial atoms, under applied magnetic field. Gaussian basis sets are used instead…
