Electron pairing: from metastable electron pair to bipolaron
Guo-Qiang Hai, Ladir Cândido, Braulio G. A. Brito +1
Starting from the shell structure in atoms and the significant correlation within electron pairs, we distinguish the exchange-correlation effects between two electrons of opposite…
New many-particle system consisting of electron pairs and holes in a two-dimensional crystal
Guo-Qiang Hai, Ladir Cândido
When atoms are organized into a crystal, the single-electron energy levels of individual atoms form energy bands. However, there also exist electron-pair states in atoms. We found…
Hamiltonian of a many-electron system with single-electron and electron-pair states in a two-dimensional periodic potential
G. -Q. Hai, F. M. Peeters
Based on the metastable electron-pair energy band in a two-dimensional (2D) periodic potential obtained previously by Hai and Castelano [J. Phys.: Condens. Matter 26, 115502 (2014)…
Metastable electron-pair states in a two-dimensional crystal
G. -Q. Hai, L. K. Castelano
We study possible quantum states of two correlated electrons in a two-dimensional crystal and find a metastable energy band of the electron pair between the two lowest single-elect…
Artificial molecular quantum rings under magnetic field influence
L. K. Castelano, G. -Q. Hai, B. Partoens +1
The ground states of few electrons confined in two vertically coupled quantum rings in the presence of an external magnetic field are studied systematically within the current spin…
Control of the persistent currents in two interacting quantum rings through the Coulomb interaction and inter-ring tunneling
L. K. Castelano, G. -Q. Hai, B. Partoens +1
The persistent current in two vertically coupled quantum rings containing few electrons is studied. We find that the Coulomb interaction between the rings in the absence of tunneli…
