Phonon wave packet emission during state preparation of a semiconductor quantum dot using different schemes
Thomas K. Bracht, Tim Seidelmann, Tilmann Kuhn +2
The carrier-phonon interaction in semiconductor quantum dots can greatly affect the optical preparation of the excited state. For resonant excitation used in the Rabi preparation s…
Quantum dynamics of optical phonons generated by optical excitation of a quantum dot
Daniel Wigger, Helge Gehring, V. Martin Axt +2
The study of the fundamental properties of phonons is crucial to understand their role in applica- tions in quantum information science, where the active use of phonons is currentl…
Dynamic vibronic coupling in InGaAs quantum dots
A. J. Brash, L. M. P. P. Martins, A. M. Barth +7
The electron-phonon coupling in self-assembled InGaAs quantum dots is relatively weak at low light intensities, which means that the zero-phonon line in emission is strong compared…
Ultrafast Depopulation of a Quantum Dot by LA-phonon-assisted Stimulated Emission
F. Liu, L. M. P. Martins, A. J. Brash +5
We demonstrate ultrafast incoherent depopulation of a quantum dot from above to below the transparency point using LA-phonon-assisted emission stimulated by a redshifted laser puls…
Effective Equations for the Precession Dynamics of Electron Spins and Electron-Impurity Correlations in Diluted Magnetic Semiconductors
Moritz Cygorek, Vollrath Martin Axt
Starting from a quantum kinetic theory for the spin dynamics in diluted magnetic semiconductors, we derive simplified equations that effectively describe the spin transfer between…
Phonon-assisted population inversion of a single quantum dot
J. H. Quilter, A. J. Brash, F. Liu +6
We demonstrate an approach to realize the population inversion of a single InGaAs/GaAs quantum dot, which is driven by a laser pulse tuned within the neutral exciton phonon sideban…
