Information

Aims, contents and method of the course

This course aims to explore the field of quantum optomechanics, part of the broader field of atomic, molecular, and optical (AMO) physics. Levitated optomechanics is at the forefront of these fields, therefore emphasis will be placed on optically trapped objects (atoms and solid-state objects). The lectures will cover fundamental concepts of quantum models of light-matter interaction and give students a firm grasp of the subject. In-depth calculations during the lectures will further deepen understanding of the most important concepts.
We will cover the following topics in the lectures:
1 Optical trapping: optical tweezers, gradient, and scattering force on dielectric nanoparticles and atoms
2 Semi-classical dynamics of systems interacting with light
3 Quantization of harmonic oscillators: input-output formalism in quantum optics, thermal bath model for quantum harmonic oscillator, decoherence
4 Quantum description of light-matter interaction
5 Optomechanics with atoms and levitated nanoparticles
6 Multimode systems: reciprocal and non-reciprocal coupling, non-Hermitian physics
7 Hybrid optomechanical systems: spins and motion
8 Quantum correlations: entanglement, squeezing, sub-SQL detection
9 Force sensing and exploring fundamental physics: dark matter sensing, gravitational wave detectors, etc.

Method: Lectures and exercises will require active participation. Lectures will be organized mostly as a knowledge transfer and occasionally as a flipped classroom. Materials will be made available to students on Moodle.

Outcome: Students will learn about research methods and current trends in quantum optomechanics and AMO physics. The students will acquire a fundamental understanding of a broad set of topics: optical trapping, power spectral densities (evaluation of system properties in frequency/Fourier domain), (quantum) harmonic oscillator and dissipation, light-matter interaction, and entanglement.

Assessment and permitted materials

Maximum number of points is 100. The final grade will be formed based on several independent evaluations of the student’s participation:
- Homework assignments will be provided during the semester. A new problem set will be announced in the lecture and the deadline will be set for two (lecture) weeks from that moment. One week into the deadline (at the lecture a week after the problem set was posted) there will be an opportunity to discuss the problems and resolve any issues regarding solutions. Students are expected to submit their solutions via Moodle before the deadline. Homework assignments will in total carry 50 points (out of 100). Note: a week without a lecture (due to public or University holidays) will not count toward the two-week countdown.
- Student conference is organized for 22.06.2023: Students will choose one scientific publication from a list provided on Moodle. Students must convey their choice to the lecturer via email at least two weeks before the student conference. Students have to prepare a 12-minute talk (10-minute talk, 2 minutes of questions) and present it at the student conference. Students are encouraged to ask questions; each question about a colleague’s talk will be rewarded with 2 bonus points. The presentation will carry 50 points (out of 100).

Minimum requirements and assessment criteria

Students have to obtain at least 50% of points in each category to pass the exam. The final grade will be calculated based on the following grading scheme:
[87.5-100]: 1
[75-87.5): 2
[62.5-75): 3
[50-62.5): 4
[0-50): you shall not pass

Examination topics

Topics covered in the lectures and exercises.

Reading list
