Partial Optomechanical Refrigeration via Multimode Cold-Damping Feedback
Christian Sommer, Claudiu Genes
We provide a fully analytical treatment for the partial refrigeration of the thermal motion of a quantum mechanical resonator under the action of feedback. As opposed to standard c…
Prospects of reinforcement learning for the simultaneous damping of many mechanical modes
Christian Sommer, Muhammad Asjad, Claudiu Genes
We apply adaptive feedback for the partial refrigeration of a mechanical resonator, i.e. with the aim to simultaneously cool the classical thermal motion of more than one vibration…
Ensemble-induced strong light-matter coupling of a single quantum emitter
Stefan Schütz, Johannes Schachenmayer, David Hagenmüller +6
We discuss a technique to strongly couple a single target quantum emitter to a cavity mode, which is enabled by virtual excitations of a nearby mesoscopic ensemble of emitters. A c…
Cavity Quantum Electrodynamics with Frequency-Dependent Reflectors
Ondřej Černotík, Aurélien Dantan, Claudiu Genes
We present a general framework for cavity quantum electrodynamics with strongly frequency-dependent mirrors. The method is applicable to a variety of reflectors exhibiting sharp in…
Laser refrigeration using exciplex resonances in gas filled hollow-core fibres
Christian Sommer, Nicolas Y. Joly, Helmut Ritsch +1
We theoretically study prospects and limitations of a new route towards macroscopic scale laser refrigeration based on exciplex-mediated frequency up-conversion in gas filled hollo…
