PhD: Micro-wave optomechanics at low temperature (M/F)

The Institut NÉEL is a CNRS unit (UPR 2940) under agreement with the University Grenoble Alpes. It is one of the largest French national research institutes for fundamental research in condensed matter physics enriched by interdisciplinary activities at the interfaces with chemistry, engineering and biology. It consists of 450 employees, including 175 researchers.
It is located in Grenoble, in the heart of a unique scientific, industrial and cultural environment, right next to the French Alpes.

The thesis will be done under the supervision of Eddy COLLIN (Director of Research CNRS). The PhD will join the ULT (Ultra-low temperatures) team, in the "Condensed Matter – Low Temperatures" (MCBT) department. The ULT team performs condensed matter experiments down to the microkelvin temperature range.

The candidate joins the ULT team work in the field of microwave opto-mechanics at low temperatures. He/she will set up and develop new opto-mechanical measurements down to the lowest possible temperatures. The aim of the thesis is to reach the quantum limit of these resonators, and study/manipulate them in these conditions.

The candidate should have a solid background in physics (including quantum mechanics), and experimental techniques. He/she should be both motivated by engineering aspects and fundamental science.

The ULT team possesses a pool of cryostats (4 Kelvin, dilution 10 milliK units, nuclear adiabatic demagnetization 100 µK). Measurement apparatuses (lock-in, bridge, vector analyser) and the required informatics are available. The technology supporting staff is provided by the laboratory.

Team work is an important component of the ULT group functioning. Experiments require handling cryofluids, and the responsibility of cryostats (dilution, nuclear demag.). Trips to conferences/collaborations shall be required.
