Comment on "Dephasing Times in Quantum Dots due to Elastic LO Phonon-Carrier Collisions"
E. A. Muljarov, R. Zimmermann
This paper is a Comment on Phys. Rev. Lett. 85, 1516 (2000) by A.V. Uskov, A.-P. Jauho, B. Tromborg, J. Mork, and R. Lang.
Near-field spectra of quantum well excitons with non-Markovian phonon scattering
G. Mannarini, R. Zimmermann
The excitonic absorption spectrum for a disordered quantum well in presence of exciton-acoustic phonon interaction is treated beyond the Markov approximation. Realistic disorder ex…
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…
Electron-Phonon Interacation in Quantum Dots: A Solvable Model
T. Stauber, R. Zimmermann, H. Castella
The relaxation of electrons in quantum dots via phonon emission is hindered by the discrete nature of the dot levels (phonon bottleneck). In order to clarify the issue theoreticall…
Optical absorption in quantum dots: Coupling to longitudinal optical phonons treated exactly
T. Stauber, R. Zimmermann
Optical transitions in a semiconductor quantum dot are theoretically investigated, with emphasis on the coupling to longitudinal optical phonons, and including excitonic effects. W…
