The experimental results are analyzed within local-spin density functional theory for which we have determined a simple lateral confining potential law that can be scaled for the different coupling regimes, and Hartree-Fock theory. Maximum density droplets composed of electrons in both bonding and antibonding or just bonding states are revealed, and interesting isospin-flip physics appears for weak interdot coupling when the systematic depopulation of antibonding states leads to changes in isospin.8 p.application/pdfeng(c) The American Physical Society, 2004Spin (Física nuclear)Diagrames de faseTeoria del funcional de densitatEstructura electrònicaSemiconductorsNuclear spinPhase diagramsDensity functional theoryElectronic structureSemiconductorsinfo:eu-repo/semantics/article518752info:eu-repo/semantics/openAccess
