Information

Ziele, Inhalte und Methode der Lehrveranstaltung

This course aims to explore the field of quantum optomechanics, part of the broader field of AMO physics. Levitated optomechanics is at the forefront of these fields, thus 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 provide students with 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 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 Hybridization of modes
7 Hybrid optomechanical systems: spins and motion
8 Quantum correlations: entanglement, squeezing, sub-SQL detection
9 Force sensing and fundamental physics

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

Outcome: Students will get acquainted with research methods in quantum optomechanics. The students will acquire fundamental understanding of 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, entanglement.

Art der Leistungskontrolle und erlaubte Hilfsmittel

Maximum number of points is 100. Final grade will be formed based on several independent evaluations of 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 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).
- Student conference on 14.06.2022: Students will choose one scientific publication from a list provided on Moodle at least two weeks before the student conference. Students will then have to prepare a 12-minute talk (10 min talk, 2 min questions) and present it in the student conference. Students are encouraged to ask questions: each question about a colleague’s talk will be rewarded with 2 points. The presentation will carry 50 points (out of 100).

Mindestanforderungen und Beurteilungsmaßstab

Students have to obtain at least 50% of points in each category in order to pass the exam. The final grade will be calculated by the following scheme:
85-100: 1
75-85: 2
65-75: 3
50-65: 4
0-50: you shall not pass

Prüfungsstoff

Topics covered in the lectures and exercises.

Literatur

Will be continuously updated on Moodle during the course.
