Nano- and optomechanics is a rapidly developing field where mechanical resonators - ranging from the nanoscale to km-sized gravitational-wave detectors - are studied with extremely sensitive methods. In this course we will study some of the most intriguing aspects of this topic, including mechanics at the nanoscale, NEMS sensors, synchronization, and quantum-limited measurements. The course consists of a lecture and exercises and will be given in English.

This semester the Nano- and Optomechanics course will be given in a hybrid format: in-presence and streaming via Zoom. Depending on the preference of the participating students and the developments of the pandemic, this may be adapted to achieve the learning outcomes in the best way.
No preconditions in addition to the requirements for the Master’s program in Physics.
After successful participation in the module, the student is able to:
- Name different designs of mechanical resonators, and of NEMS and optomechanical detectors. Tell what their main pros and cons are.
- Illustrate the difference between bottom-up and top-down devices.
- Recall the optomechanical Hamiltonian and the derivation of its limiting cases. Evaluate the outcome with different quantum mechanical states.
- Classify different damping mechanism in mechanical devices and relate this to force noise and temperature.
- Select the right material(s) for a resonator+detector design, based on an understanding of the fabrication techniques and material properties
- Explain the working principle of different detector schemes. Distinguish its detection- and back action mechanisms
- Model the interaction between a detector and the resonator. Discover how this leads to the standard quantum limit (SQL), quantum non-demolition (QND) measurements, and optomechanically-induced transparency (OMIT).
- Outline different cooling mechanism and evaluate the final temperature of a cooling experiment.
- Analyze the properties of simple (e.g. string, beam) and more complex (e.g. H) mechanical structures.
- Assess the feasibility of a given design of an optomechanical sensor for small and large motion amplitudes.
- Plan an experiment to measure one of the effects discussed in the module.
