Abstract: We present a theory of laterally coupled quantum Hall droplets with electron numbers (N1,N2) at filling factor ν = 2. We show that the edge states of each droplet are tunnel coupled and form a two-level artificial molecule. By populating the edge states with one electron each a two electron molecule is formed. We predict the singlet-triplet transitions of the effective two-electron molecule as a function of the magnetic field, the number of electrons, and confining potential using the configuration interactio…
