Cooperative quantum phenomena in light-matter platforms
Michael Reitz, Christian Sommer, Claudiu Genes
Quantum cooperativity is evident in light-matter platforms where quantum emitter ensembles are interfaced with confined optical modes and are coupled via the ubiquitous electromagn…
Molecular polaritonics in dense mesoscopic disordered ensembles
Christian Sommer, Michael Reitz, Francesca Mineo +1
We study the dependence of the vacuum Rabi splitting (VRS) on frequency disorder, vibrations, near-field effects and density in molecular polaritonics. In the mesoscopic limit, sta…
Multimode cold-damping optomechanics with delayed feedback
Christian Sommer, Alekhya Ghosh, Claudiu Genes
We investigate the role of time delay in cold-damping optomechanics with multiple mechanical resonances. For instantaneous electronic response, it was recently shown in \textit{Phy…
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…
