Path integral description of combined Hamiltonian and non-Hamiltonian dynamics in quantum dissipative system
A. M. Barth, A. Vagov, V. M. Axt
We present a numerical path-integral iteration scheme for the low dimensional reduced density matrix of a time-dependent quantum dissipative system. Our approach simultaneously acc…
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…
Fast and selective phonon-assisted state preparation of a quantum dot by adiabatic undressing
A. M. Barth, S. Lüker, A. Vagov +3
We investigate theoretically the temporal behavior of a quantum dot under off-resonant optical excitation targeted at fast acoustic phonon-assisted state preparation. We demonstrat…
