An optomechanical disk in its fundamental state of motion

An optomechanical disk in its fundamental state of motion

The motion of a mesoscopic mechanical resonator can exhibit quantum behavior when cooled to very low temperatures. In particular, it can reach its ground state and cease to vibrate. Using light as a probe, the LIME team at the MPQ laboratory demonstrated that...
Exact low-energy duality in superconducting quantum circuits

Exact low-energy duality in superconducting quantum circuits

The THEORIE team, in collaboration with Michel H. Devoret, has published a theoretical study in Physical Review Letters demonstrating an exact low-energy duality in circuits where a Josephson junction is coupled to a multi-mode environment. These systems exhibit a...
