Molecule-photon interactions in phononic environments
Michael Reitz, Christian Sommer, Burak Gurlek +3
Molecules constitute compact hybrid quantum optical systems that can interface photons, electronic degrees of freedom, localized mechanical vibrations and phonons. In particular, t…
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…
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…
