Electronic States of Magnetic Quantum Dots
Ramin M. Abolfath, Pawel Hawrylak, Igor Zutic
We study quantum states of electrons in magnetically doped quantum dots as a function of exchange coupling between electron and impurity spins, the strength of Coulomb interaction,…
Piezomagnetic Quantum Dots
Ramin M. Abolfath, Andre Petukhov, Igor Zutic
We study the influence of deformations on magnetic ordering in quantum dots doped with magnetic impurities. The reduction of symmetry and the associated deformation from circular t…
Quantum Hall Ferrimagnetism in lateral quantum dot molecules
Ramin M. Abolfath, Pawel Hawrylak
We demonstrate the existance of ferrimagnetic and ferromagnetic phases in a spin phase diagram of coupled lateral quantum dot molecules in the quantum Hall regime. The spin phase d…
Quantum Hall droplets in coupled lateral quantum dots
Ramin M. Abolfath, Pawel Hawrylak, Michel Pioro-Ladriere +1
We present a theory and Coulomb and Spin Blockade spectroscopy experiments on quantum Hall droplets with controlled electron numbers (N1,N2) in laterally coupled gated quantum dots…
Real Space Hartree-Fock Configuration Interaction Method For Complex Lateral Quantum Dot Molecules
Ramin M. Abolfath, Pawel Hawrylak
We present unrestricted Hartree Fock method coupled with configuration interaction (CI) method (URHF-CI) suitable for the calculation of ground and excited states of large number o…
Theory of a two-level artificial molecule in laterally coupled quantum Hall droplets
Ramin M. Abolfath, W. Dybalski, Pawel Hawrylak
We present a theory of laterally coupled quantum Hall droplets with electron numbers (N1,N2) at filling factor . We show that the edge states of each droplet are tunnel couple…
