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,…
Two level anti-crossings high up in the single-particle energy spectrum of a quantum dot
C. Payette, D. G. Austing, G. Yu +5
We study the evolution with magnetic field of the single-particle energy levels high up in the energy spectrum of one dot as probed by the ground state of the adjacent dot in a wea…
Magnetic field induced effects in the high source-drain bias current of weakly coupled vertical quantum dot molecules
D. G. Austing, C. Payette, G. Yu +1
We report on the basic properties of recently observed magnetic field resonance, induced time dependent oscillation, and hysteresis effects in the current flowing through two weakl…
Many-body excitations in tunneling current spectra of a few-electron quantum dot
D. V. Melnikov, T. Fujisawa, D. G. Austing +2
Inherent asymmetry in the tunneling barriers of few-electron quantum dots induces intrinsically different tunneling currents for forward and reverse source-drain biases in the non-…
Optical readout of charge and spin in a self-assembled quantum dot in a strong magnetic field
M. Korkusinski, P. Hawrylak, A. Babinski +3
We present a theory and experiment demonstrating optical readout of charge and spin in a single InAs/GaAs self-assembled quantum dot. By applying a magnetic field we create the fil…
Influence of the single-particle Zeeman energy on the quantum Hall ferromagnet at high filling factors
B. A. Piot, D. K. Maude, M. Henini +10
In a recent paper [B. A. Piot et al., Phys. Rev. B 72, 245325 (2005)], we have shown that the lifting of the electron spin degeneracy in the integer quantum Hall effect at high fil…
