Theory that feeds into our experiments

Our theory collaborators, both for the optomechanics and the levitation experiments, have uploaded new works to the arxiv.

Lei Du, together with Juliette Monsel, from Janine Splettstoessers group has outlined the theory how to create nonclassical optomechanical states in a Fano-optomechanical microcavity system, see here. This work serves as an inspiration for our ongoing efforts in achieving nonlinear optomechanics.

Jaume Cunill-Subiranas, together with Natanael Bort-Soldevila, from the team of Nuria Del-Valle and Carles Navau have shown how to create any magneto-static field using an arrangement of superconductors, high permeability materials and an arbitrary magnetic field source. We, in particular Fabian Resare from our lab, have contributed to this work with a proof-of-principle experiment demonstrating the feasibility of the suggested approach. Interested? Look here.

Tuning of flux tunable superconducting resonators

Our lab’s first flux-tunable superconducting resonators are now on arXiv. We show how one can efficiently modulate these FTRs using chip-based modulation techniques. This work is part of our group’s efforts to generate macroscopic quantum states of levitated superconducting microparticles.

Thanks to the efforts from our group by Achintya Paradkar (main actor!), Paul Nicaise, Karim Dakroury and Fabian Resare, and by our co-workers from the EU project SuperMeQ Christian Dejaco, Lukas Deeg and Gerhard Kirchmair.

I want to also thank Amr Osman, Anita Fadavi and Jonas Bylander for the strong support in microfabrication we have received at the Quantum Technology lab at Chalmers Department of Microtechnology and Nanoscience at Chalmers University of Technology.

Welcome Aditi!

We welcome Aditi to our lab, who joins the maglev team as a PhD student. She will research on the read-out and control of levitated superconducting microparticles based on superconducting circuit technology. This will be much fun!
