Phys. Rev. B 79, 075301 (2009) [5 pages]Effects of thickness in quantum dots in strong magnetic fieldsReceived 30 September 2008; revised 15 December 2008; published 2 February 2009 We study the effects of thickness on the ground states of two-dimensional quantum dots in high magnetic fields. To be specific, we assume the thickness to be small so that only the lowest state in the corresponding direction is occupied, which however leads to a modification of the effective interaction between the electrons. We find the ground-state phase diagram and demonstrate the emergence of different phases as the thickness is accounted for. Finally, the wave-functional form and vortex structure of different phases are analyzed. © 2009 The American Physical Society URL:
