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…
Mapping between quantum dot and quantum well lasers: From conventional to spin lasers
Jeongsu Lee, Rafał Oszwałdowski, Christian Gøthgen +1
We explore similarities between the quantum wells and quantum dots used as optical gain media in semiconductor lasers. We formulate a mapping procedure which allows a simpler, ofte…
