Description of the thesis topic
Access to sub-mK temperatures is essential to the advancement of the interacting fields of quantum technology, nanoscience, and quantum materials. Present cooling technologies in this temperature range have very limited experimental space or cold times of less than 100 hours.
For example, bulky microwave components that are required for detecting the zero-point motion of nanomechanical resonators are difficult to accommodate in existing cryostats.
In this PhD project, the student will contribute to the development of a continuous nuclear demagnetization refrigerator precooled by a cryogen-free dilution refrigerator. This cryostat will offer expansive experimental space and indefinite measurement times. The student will also use the techniques of microwave optomechanics to probe the dynamics of nanomechanical resonators cooled to mK or even microK temperatures.
The Institut Néel is a condensed matter physics laboratory in Grenoble. It consists of 450 employees, including 175 researchers. The research activities are centered on fundamental condensed matter physics and also include some chemistry, engineering and life sciences. The Insitute possesses technological expertise at the highest level, which is crucial for research projects carried out here. While the research is primarily experimental, it also relies on strong abilities in analytical and numerical theoretical physics.
