Asymmetry in self-assembled quantum dot-molecules made of identical InAs/GaAs quantum dots
Lixin He, Gabriel Bester, Alex Zunger
We show that a diatomic dot molecule made of two identical, vertically stacked, strained InAs/GaAs self-assembled dots exhibits an asymmetry in its single-particle and may-particle…

Theory of excitonic spectra and entanglement engineering in dot molecules
Gabriel Bester, J. Shumway, Alex Zunger
We present results of correlated pseudopotential calculations of an exciton in a pair of vertically stacked InGaAs/GaAs dots. Competing effects of strain, geometry, and band mixing…

Metal-nonmetal transition and excitonic ground state in InAs/InSb quantum dots
Lixin He, Gabriel Bester, Alex Zunger
Using atomistic pseudopotential and configuration-interaction many-body calculations, we predict a metal-nonmetal transition and an excitonic ground state in the InAs/InSb quantum…
