Many-body physics in Josephson quantum circuits |
|
Résumé |
Superconducting Josephson waveguides are introduced as a promising platform for engineering quantum many-body states. We investigate both experimentally and theoretically the on-chip realization of various models for an open quantum system, where its environment is perfectly controlled and measurable. In the strong interaction regime, the quantum system experiences a well-known renormalization, that can be extracted from spectroscopic measurements. We also put into evidence a more subtle back-action associated to the inelastic scattering of the environmental modes on the quantum system. Several theoretical methods, both perturbative and non-perturbative, are presented to describe these effects. |
