Few-photons model of the optical emission of semiconductor quantum dots
Marten Richter, Alexander Carmele, Anna Sitek +1
The Jaynes-Cummings model provides a well established theoretical framework for single electron two level systems in a radiation field. Similar exactly solvable models for semicond…
Theory of nonlinear optical response of ensembles of double quantum dots
Anna Sitek, Pawel Machnikowski
We study theoretically the time-resolved four-wave mixing (FWM) response of an ensemble of pairs of quantum dots undergoing radiative recombination. At short (picosecond) delay tim…
Interplay of coupling and superradiant emmision in the optical response of a double quantum dot
Anna Sitek, Pawel Machnikowski
We study theoretically the optical response of a double quantum dot structure to an ultrafast optical excitation. We show that the interplay of a specific type of coupling between…
Four wave mixing spectroscopy of quantum dot molecules
A. Sitek, P. Machnikowski
We study theoretically the nonlinear four wave mixing (FWM) response of an ensemble of coupled pairs of quantum dots (quantum dot molecules). We discuss the shape of the FWM echo s…
Collective fluorescence and decoherence of a few nearly identical quantum dots
Anna Sitek, Pawel Machnikowski
We study the collective interaction of excitons in closely spaced artificial molecules and arrays of nearly identical quantum dots with the electromagnetic modes. We discuss how co…
