Multi-spin errors in the optical control of a spin quantum memory
Michal Grochol, Carlo Piermarocchi
We study a quantum memory composed of an array of charged quantum dots embedded in a planar cavity. Optically excited polaritons, i.e. exciton-cavity mixed states, interact with th…
Microcavity polaritons in disordered exciton lattices
Michal Grochol, Carlo Piermarocchi
We investigate the interaction of excitons in a two dimensional lattice and photons in a planar cavity in the presence of disorder. The strong exciton-photon coupling is described…
Light-mass Bragg cavity polaritons in planar quantum dot lattices
E. M. Kessler, M. Grochol, C. Piermarocchi
The exciton-polariton modes of a quantum dot lattice embedded in a planar optical cavity are theoretically investigated. Umklapp terms, in which an exciton interacts with many cavi…
Non-circular semiconductor nanorings of type I and II: Emission kinetics in the exciton Aharonov-Bohm effect
Michal Grochol, Roland Zimmermann
Transition energies and oscillator strengths of excitons in dependence on magnetic field are investigated in type I and II semiconductor nanorings. A slight deviation from circular…
Optical exciton Aharonov-Bohm effect, persistent current, and magnetization in semiconductor nanorings of type I and II
M. Grochol, F. Grosse, R. Zimmermann
The optical exciton Aharonov-Bohm effect, i. e. an oscillatory component in the energy of optically active (bright) states, is investigated in nanorings. It is shown that a small e…
