Time-resolved magnetophotoluminescence studies of magnetic polaron dynamics in type-II quantum dots
B. Barman, R. Oszwałdowski, L. Schweidenback +12
We used continuous wave photoluminescence (cw-PL) and time resolved photoluminescence (TR-PL) spectroscopy to compare the properties of magnetic polarons (MP) in two related spatia…
Magnetic ordering in quantum dots: Open vs. closed shells
J. M. Pientka, R. Oszwałdowski, A. G. Petukhov +2
In magnetically-doped quantum dots changing the carrier occupancy, from open to closed shells, leads to qualitatively different forms of carrier-mediated magnetic ordering. While i…
Large Stark Effect for Li Donor Spins in Si
Luke Pendo, E. M. Handberg, V. N. Smelyanskiy +1
We study the effect of a static electric field on lithium donor spins in silicon. The anisotropy of the effective mass leads to the anisotropy of the quadratic Stark susceptibility…
Reentrant Formation of Magnetic Polarons in Quantum Dots
J. M. Pientka, R. Oszwałdowski, A. G. Petukhov +2
We propose a model of magnetic polaron formation in semiconductor quantum dots doped with magnetic ions. A wetting layer serves as a reservoir of photo-generated holes, which can b…
Spin ordering in magnetic quantum dots: From core-halo to Wigner molecules
R. Oszwałdowski, P. Stano, A. G. Petukhov +1
The interplay of confinement and Coulomb interactions in quantum dots can lead to strongly correlated phases differing qualitatively from the Fermi liquid behavior. We explore how…
Magnetic anisotropies of quantum dots
Karel Vyborny, J. E. Han, Rafal Oszwaldowski +2
Magnetic anisotropies in quantum dots (QDs) doped with magnetic ions are discussed in terms of two frameworks: anisotropic -factors and magnetocrystalline anisotropy energy. It…
Magnetism in Closed-shell Quantum Dots: Emergence of Magnetic Bipolarons
R. Oszwałdowski, I. Žutić, A. G. Petukhov
Similar to atoms and nuclei, semiconductor quantum dots exhibit formation of shells. Predictions of magnetic behavior of the dots are often based on the shell occupancies. Thus, cl…
Robust Magnetic Polarons in Type-II (Zn,Mn)Te Quantum Dots
I. R. Sellers, R. Oszwaldowski, V. R. Whiteside +7
We present evidence of magnetic ordering in type-II (Zn, Mn) Te quantum dots. This ordering is attributed to the formation of bound magnetic polarons caused by the exchange interac…
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…
