Rasul Gazizulin – Low Temperature Experiment Candidate Seminar

On-chip mechanical thermometry at mK temperatures

With the aim of measuring on-chip the phonon temperature of a mechanical nano-oscillator, we have set up an optomechanical system where a long mechanical beam is coupled to a microwave cavity. The experiment is mounted on the Grenoble nuclear demagnetisation cryostat able to reach temperatures below

1 mK. We report on the first measurements of this set-up at dilution temperatures, and discuss future possibilities for ultra-cold nanomechanics where cooling relies only on cryogenic technologies. No active cooling techniques are used in our experiments, in which we explore the limits of “brute force”. cooling for these systems.
