Positions in Vienna and Innsbruck
The Vienna and Innsbruck teams have open theory PhD and postdoc positions.
Part of the work will be to collaborate with the Copenhagen, Torun and Amsterdam teams to realize superradiant clocks on the kHz and mHz line of strontium (Task 2 and 3). At the beginning of the project realistic operation parameters must be determined. Once the experiments exist, the experimentalists will need guidance to reach the regime of steady-state superradiance. Together with the Amsterdam team we will study the foundations of superradiant lasing, which could include cooling and repumping techniques, cavity cooling of a beam of thermal atoms to form a continuous atom laser, or the quantum many-body physics of driven-dissipative systems (Task 4).
In order to pursue these tasks we will perform extensive theoretical investigations of the foundations of superradiant lasers and create a dedicated theoretical and computational toolbox for a quantitative simulation of superradiant lasers and cavity enhanced spectroscopy, particularly as an extension to the Quantum-Optics package qojulia.org developed by the Innsbruck team, and investigate, both theoretically and experimentally, new implementations.
We will analyse the performance of the experiments built by the Copenhagen, Torun and Amsterdam partners and select the most significant real-life effects that need further study, such as: the multilevel structure of the states coupled to the cavity field, inhomogeneous broadening, decoherence due to various reasons, dipole-dipole interactions, collective light shifts, inhomogeneity of the coupling of the atoms to the cavity, motion of the atoms through the cavity waist, etc. Then these real-life effects will be investigated separately using different approximation models. This study will allow us to find appropriate approximations to simulation of superradiant lasers and cavity enhanced spectroscopy in the presence of these effects. Comparing various approaches allows to find limits of validity of these approximations. Based upon those studies we will build integrated computational models of the systems developed by the experimental partners. These models will be used for detailed investigations and optimizations of the operational regimes of these systems, furthermore, comparison between theory and experiment will allow to continuously improve the simulation models. Also, we plan to characterise new implementations of superradiant lasers in pulsed or CW operation. We will simulate novel implementation geometries with build-in repumping and cooling schemes to estimate their linewidth and power.
