Semiconductor quantum wells excited by non-classical states of light: Interplay between photonic quantum correlations and many-body interactions in solid state systems
Final Report Abstract
In this project, we developed and analyzed a theoretical approach which describes the lightmatter interaction between semiconductors and light on a fully quantized level. This means that the dynamics of the material excitations and the light field are described self-consistently and that the light field is described in terms of its fundamental elementary quantum mechanical excitations, i.e., photons. Our approach was applied to different model systems and scenarios. Firstly, we analyzed a Jaynes-Cummings–type model with three electronic states which is excited by quantum light. We demonstrated that losses, which are unavoidable in real systems, can be used to control the population of the electronic states. Furthermore, electromagnetically induced transparency in the presence of quantum light was demonstrated and quantum correlations between light fields were studied. Secondly, the interaction between quantum light and matter was studied for systems that are enclosed in low-Q cavities which generally receive less attention due to their high losses that quickly destroy quantum properties. By analyzing a Λ-type three-level system in lossy cavities, we, however, demonstrated that low-Q cavities can be beneficial for preparing specific electronic steady states when specific quantum states of light are applied. Thirdly, quantum-optical properties of one- and two-dimensional semiconductor nanostructures were studied for a two-band tight-binding model. We demonstrated that during the interaction process, a collective excitation of the conduction band is formed. For nonresonant excitations, this collective dynamics results in interesting steady states in which the resonantly addressed eigenstates are occupied. Recently this model was extended to incorporate excitonic effects. Within this project we obtained several relevant results for different model systems and predicted novel effects. In suitably designed systems, our findings should be observable in experiment. The predicted properties could be useful for future applications in quantum technologies and devices which take advantage of both photonic quantum correlations and quantum correlations between light and matter.
