Electron-Phonon Interaction in Embedded Semiconductor Nanostructures
Frank Grosse, Roland Zimmermann
The modification of acoustic phonons in semiconductor nanostructures embedded in a host crystal is investigated including corrections due to strain within continuum elasticity theo…
LO Phonon-Induced Exciton Dephasing in Quantum Dots: An Exactly Solvable Model
E. A. Muljarov, R. Zimmermann
It is widely believed that, due to its discrete nature, excitonic states in a quantum dot coupled to dispersionless LO phonons form everlasting mixed states (exciton polarons) show…
Memory and correlation effects in the exciton-phonon kinetics
G. Mannarini, R. Zimmermann
Memory and correlation effects in the interband absorption from quantum wells due to exciton-phonon dynamics are investigated. They are traced back to the frequency dependence and…
Nonlinear optical response and exciton dephasing in quantum dots
E. A. Muljarov, R. Zimmermann
The full time-dependent four-wave mixing polarization in quantum dots is microscopically calculated, taking into account acoustic phonon-assisted transitions between different exci…
Dynamical T-matrix theory for high-density excitons in coupled quantum wells
R. Zimmermann
Excitons in coupled quantum wells open the possibility to reach high densities close to equilibrium. In a recent experiment employing a lateral trap potential, a blue shift and a b…
