If you are interested in macroscopic quantum systems, in arxiv.org/abs/2407.02453 we ground state cool the bright collective mode of 6 mechanical resonators optomechanically coupled to a microwave cavity. We also show collective enhancement of optomechanical damping rate!

We have two fully-funded, 2-year postdoc positions open in my laboratory at Chalmers, one in spin sensing with ultralow-loss mechanical resonators and one on creating hybrid quantum systems of single atoms and optomechanical systems.

Our latest publication is out today! We demonstrate a novel protocol to generate real mechanical excitations by modulating the ultrastrong vacuum of a coupled qubit-cavity system. Dive into the details here: scipost.org/SciPostPhys.17…
